(1) And for slanderers may there be no hope; and may all wickedness be destroyed instantly and may all Your enemies be cut down quickly. Quickly uproot, smash, and cast down the arrogant sinners and humble them quickly in our days. Blessed are You, O Lord, Who breaks enemies and humbles arrogant sinners.
ת"ר ארבעה נכנסו בפרדס ואלו הן בן עזאי ובן זומא אחר ורבי עקיבא אמר להם ר"ע כשאתם מגיעין אצל אבני שיש טהור אל תאמרו מים מים משום שנאמר (תהלים קא, ז) דובר שקרים לא יכון לנגד עיני בן עזאי הציץ ומת עליו הכתוב אומר (תהלים קטז, טו) יקר בעיני ה' המותה לחסידיו בן זומא הציץ ונפגע ועליו הכתוב אומר (משלי כה, טז) דבש מצאת אכול דייך פן תשבענו והקאתו אחר קיצץ בנטיעות רבי עקיבא יצא בשלום
The Sages taught: Four entered the orchard [pardes], i.e., dealt with the loftiest secrets of Torah, and they are as follows: Ben Azzai; and ben Zoma; Aḥer, the other, a name for Elisha ben Avuya; and Rabbi Akiva. Rabbi Akiva, the senior among them, said to them: When, upon your arrival in the upper worlds, you reach pure marble stones, do not say: Water, water, although they appear to be water, because it is stated: “He who speaks falsehood shall not be established before My eyes” (Psalms 101:7). The Gemara proceeds to relate what happened to each of them: Ben Azzai glimpsed at the Divine Presence and died. And with regard to him the verse states: “Precious in the eyes of the Lord is the death of His pious ones” (Psalms 116:15). Ben Zoma glimpsed at the Divine Presence and was harmed, i.e., he lost his mind. And with regard to him the verse states: “Have you found honey? Eat as much as is sufficient for you, lest you become full from it and vomit it” (Proverbs 25:16). Aḥer chopped down the shoots of saplings. In other words, he became a heretic. Rabbi Akiva came out safely.

(6) And, the following are they that have no share in the World to Come but suffer excision and loss of identity, and are damned for ever and ever for their exceeding wickedness and sinfulness: atheists, infidels, traducers of the Torah, dissenters of resurrection and the coming of a Redeamer, apostates, enticers of many to sin, seceders from the congregation, a public perpetrator of sins emulating Jehoiakim,8See II. Kings, 23.36–24.6 G. informers, leaders who cast fear upon the congregation not for the sake of God, shedders of blood by defaming people in public, evil-tongued people, he who abolishes circumcision.9Rosh ha-Shanah, 17a. G.
(7) There are five categories of atheists;10Minim. G. (1) he who says that there is no God and no Omnipotence; (2) he who says that there is an Omnipotence but that there are two or more such; (3) he who says that there is One Lord; but that He is corporeal and has a form; (4) Likewise one who says that He alone is not the First Cause and Creator of all; (5) likewise he who worships a star, or planet, or any other as a mediator between him and the Lord of the universe; every one of these five is an atheist.13Sanhedrin, 26b. C.
(8) There are three categories of infidels: (1) he who says that prophecy is altogether an invention, and that no knowledge reaches the heart of the sons of man from the Creator; (2) he who denies the prophecy of Moses our Master; (3) and he who says that the Creator knoweth not the affairs of the sons of man; every one of these three is an infidel. There are three categories of Torah traducers: (1) he who says that the Torah is not God given, even if he says that a single Verse or one word thereof was spoken by Moses on his own authority is, indeed, a traducer of the Torah; (2) he who denies its Oral explanation, that is the Oral Torah, or its exponents, even as Zaduk and Bythos did;14See Abot D’Rabbi Nathan, Ch.5; also I. Chro. 5.3G. (3) he who says that the Creator commuted this Duty for another duty and that the Torah had been nullified long ago though it really was God given; every one of these three is a traducer of the Torah.15Sanhedrin, 90a; Ibid. 99b. C.
(9) There are two categories of apostates in Israel: (1) an apostate against one commandment; (2) an apostate against the whole Torah. The apostate against one commandment is; one who emboldens himself to transgress a given commandment consciously so that it becomes his habit of doing it publicly, even it be of the minor commandments, for instance, he persistently wears garment mixed of wool and flax, or rounds the corners of his head, as a consequence whereof it appears that such commandment no longer exists in his world, such one is, indeed, an apostate in this matter, if he does such spitefully. An apostate against the whole Torah is, a convert to the religion of the idolaters, for instance, at a time when they issue arbitrary edicts and he cleaves to them, saying: "Of what profit is there for me to cleave to Israel who are down-trodden and persecuted; it is rather best for me to cleave to these in whose hand lies the power", he, assuredly, is apostate against the whole Torah.17Hullin, 5; Sanhedrin, 26b. C.
The Lords of the ma'amad, having long known of the evil opinions and acts of Baruch de Espinoza, have endeavoured by various means and promises, to turn him from his evil ways. But having failed to make him mend his wicked ways, and, on the contrary, daily receiving more and more serious information about the abominable heresies which he practised and taught and about his monstrous deeds, and having for this numerous trustworthy witnesses who have deposed and borne witness to this effect in the presence of the said Espinoza, they became convinced of the truth of the matter; and after all of this has been investigated in the presence of the honourable chachamin [sages], they have decided, with their consent, that the said Espinoza should be excommunicated and expelled from the people of Israel. By the decree of the angels, and by the command of the holy men, we excommunicate, expel, curse and damn Baruch de Espinoza, with the consent of God, Blessed be He, and with the consent of all the Holy Congregation, in front of these holy Scrolls with the six-hundred-and-thirteen precepts which are written therein, with the excommunication with which Joshua banned Jericho, with the curse with which Elisha cursed the boys and with all the curses which are written in the Book of the Law. Cursed be he by day and cursed be he by night; cursed be he when he lies down, and cursed be he when he rises up; cursed be he when he goes out, and cursed be he when he comes in. The Lord will not spare him; the anger and wrath of the Lord will rage against this man, and bring upon him all the curses which are written in this book, and the Lord will blot out his name from under heaven, and the Lord will separate him to his injury from all the tribes of Israel with all the curses of the covenant, which are written in the Book of the Law. But you who cleave unto the Lord God are all alive this day. We order that no one should communicate with him orally or in writing, or show him any favour, or stay with him under the same roof, or within four ells of him, or read anything composed or written by him.

According to his own testimony, Josephus was a Jewish general who surrendered to the Romans and became a prominent intellectual in Rome. Was he a traitor or a victim? Is he an accurate representative of rabbinic Judaism or a deviant? Surprisingly, the Talmud offers no opinion about him. R. Joseph B. Soloveitchik (Kinos Mesoras Ha-Rav, pp. 279-280) offers the following explanation of the Talmudic attitude toward Josephus:
The Jews under Josephus’ command fought heroically, but gradually the garrison of defenders was isolated and decimated by hunger. With no hope left, the warriors under Josephus’ command entered into a suicide pact rather than surrendering and falling into enemy hands. They drew lots and killed themselves one by one. Rather than committing suicide, however, Josephus surrendered to the Romans. He was taken prisoner and ultimately became a Roman citizen and was close with the Roman imperial family.
I would not say that Josephus lacked the courage to commit suicide. From a halakhic point of view, Josephus may not have been permitted to do so. The Midrash clearly says (Bereshit Rabba 34:13) that committing suicide is an act of murder. The case of King Saul causing himself to be killed is explained by some as an exception to this prohibition because Saul realized that the enemy would kill him imminently in any event. Therefore, if Josephus realized that he was not in imminent danger of being killed by the Romans, he would not have been halakhically permitted to kill himself. Nonetheless, one could argue that even though halakha may not have required Josephus to commit suicide, under halakha, one may commit suicide to avoid surrendering to the enemy. If so, such discretion would have been available to Josephus as well. In summary, I am not certain that Josephus committed an act of betrayal. He may have been acting in accordance with the prohibition against suicide.
It is interesting that Josephus is not mentioned at all in the Gemara, although Rashi does refer to him (Bava Batra 3b, s.v., hekhi). Our sages make no mention of the incident despite their extensive discussion of the events of the Second Temple period. It is hard to know what the attitude of our sages was, but I suspect that while they disapproved of what Josephus did, they felt that they did not have the right to condemn him. As a result, they ignored him. The Gemara would have mentioned him if it considered him a traitor.

Article about attempts to silence Breaking the Silence:
"The small whistleblower organization has found itself at the epicenter of a well-orchestrated, ongoing campaign by a spectrum of right-wing groups, individuals, media outlets, and senior politicians to quash its exposure of Israel’s occupation and human rights violations. The attacks have included incitement and threats. They have been called liars, traitors, and enemies.
The political persecution of Breaking the Silence is a testament to the settler right’s consolidation of power and permeation into the mainstream.
For the right, the attacks against Breaking the Silence make sense. The military is revered in Israel, and elite combat soldiers who question or challenge their service in the occupied territories represent the most effective wrench in the institutionalization of Israel’s system of control in the West Bank and Gaza. As one of the sole voices in Israel speaking consistently and clearly against the occupation, a bright red target has been placed on the group’s back."

(71) For informers let there be no hope34This petition was added to the original Eighteen Benedictions. It was ordained by Rabban Gamliel and his Bais Din in Yavneh, according to the text of Shmuel HaKattan, its author (Maseches Berachos 28:b). It is directed against the early Christians who informed against Jews to the Roman authorities after the destruction of the Second Temple, causing them to be put to an excruciatingly painful death. and may all wickedness35Not the “wicked,” but “wickedness.” This particular prayer is based on the Talmudic interpretation of the verse, “Let sins be terminated on earth and the wicked will be no more” (Psalms 104:36). instantly perish may all Your enemies36God's enemies are the enemies of His people (see Rashi to Numbers 31:3). The internal enemies of the Jews, against whom this prayer was originally directed, disappeared within a short time. be swiftly cut off, and the insolent may You quickly uproot, crush, rout, disgrace and humbled and subdue speedily in our days. Blessed are You, Adonoy, Crusher of enemies and Subduer of the insolent.
