(5) But for your own life-blood I will require a reckoning: I will require it of every beast; of man, too, will I require a reckoning for human life, of every man for that of his fellow man!
(יא) הַמְאַבֵּד עַצְמוֹ לָדַעַת אֵין מִתְעַסְּקִין עִמּוֹ לְכָל דָּבָר וְאֵין מִתְאַבְּלִין עָלָיו וְאֵין מַסְפִּידִין אוֹתוֹ. אֲבָל עוֹמְדִין עָלָיו בְּשׁוּרָה וְאוֹמְרִין עָלָיו בִּרְכַּת אֲבֵלִים וְכָל דָּבָר שֶׁהוּא כָּבוֹד לַחַיִּים. וְאֵי זֶהוּ הַמְאַבֵּד עַצְמוֹ לָדַעַת. לֹא שֶׁעָלָה לַגַּג וְנָפַל וּמֵת אֶלָּא הָאוֹמֵר הֲרֵינִי עוֹלֶה לְרֹאשׁ הַגַּג. רָאוּהוּ שֶׁעָלָה מִיָּד דֶּרֶךְ כַּעַס אוֹ שֶׁהָיָה מֵצֵר וְנָפַל וּמֵת. הֲרֵי זֶה בְּחֶזְקַת שֶׁאִבֵּד עַצְמוֹ לָדַעַת. אֲבָל אִם רָאוּהוּ חָנוּק וְתָלוּי בָּאִילָן אוֹ הָרוּג וּמֻשְׁלָךְ עַל גַּב סֵיפוֹ הֲרֵי זֶה בְּחֶזְקַת כָּל הַמֵּתִים וּמִתְעַסְּקִין עִמּוֹ וְאֵין מוֹנְעִין מִמֶּנּוּ דָּבָר:
(11) When a person commits suicide [kills oneself with clarity of mind], we do not engage in activity on their behalf at all. We do not mourn for him or eulogize him. We do, however, stand in a line to comfort the relatives, recite the blessing for the mourners and perform any act that shows respect for the living. What is meant by a person who commits suicide? Not necessarily one who climbs up on a roof, falls, and dies, but rather, one who says: "I am going up to the top of the roof." If we see him climb up immediately in anger or know that he was distressed and see him fall and die, we presume such a person is one who committed suicide. If, however, we see him strangled and hanging from a tree or slain and lying on the back of his sword, we presume that he is like all other corpses. We engage in activity on his behalf and do not withhold anything from him.
Aruch Hashulchan [19th Century]
“Generally, when someone takes his own life we blame it on any reason at all, for instance, fear or troubles, or insanity, or the belief that suicide is a better alternative than getting involved in other transgressions, etc. Suicide is truly a remote prospect for a person in his right mind. Learn from the example of Saul the Righteous who fell on his own sword, so that the Philistines would not torment him, and there are other similar possibilities of unbearable stress. And certainly when it is a minor who commits suicide, we consider it involuntary”.34
