According to Rashi, Judah will be an outcast in Two Worlds if Benjamin is kept as a slave instead of him. What two worlds?
(ה) מַזְכִּירִין יְצִיאַת מִצְרַיִם בַּלֵּילוֹת. אָמַר רַבִּי אֶלְעָזָר בֶּן עֲזַרְיָה, הֲרֵי אֲנִי כְּבֶן שִׁבְעִים שָׁנָה, וְלֹא זָכִיתִי שֶׁתֵּאָמֵר יְצִיאַת מִצְרַיִם בַּלֵּילוֹת, עַד שֶׁדְּרָשָׁהּ בֶּן זוֹמָא, שֶׁנֶּאֱמַר (דברים טז) לְמַעַן תִּזְכֹּר אֶת יוֹם צֵאתְךָ מֵאֶרֶץ מִצְרַיִם כֹּל יְמֵי חַיֶּיךָ. יְמֵי חַיֶּיךָ, הַיָּמִים. כֹּל יְמֵי חַיֶּיךָ, הַלֵּילוֹת. וַחֲכָמִים אוֹמְרִים, יְמֵי חַיֶּיךָ, הָעוֹלָם הַזֶּה. כֹּל יְמֵי חַיֶּיךָ, לְהָבִיא לִימוֹת הַמָּשִׁיחַ:
(5) One must mention the exodus from Egypt at night. Rabbi Elazar ben Azaryah said: "Behold, I am like a seventy-year-old man, yet I could not win [the argument against the other sages] having the exodus from Egypt recited at night, until Ben Zoma derived it [from a Biblical source]." "[He derived it as follows:] It says (Deut. 16:3), 'In order that you may remember the day when you left Egypt for all the days of your life.'" "Now, 'days of your life' means the days; 'All the days of your life' [includes also] the nights." But the Sages say: "Days of your life" means the present world; "All the days of your life" includes also the era of Mashiach.
Shlomo Yitzchaki (Hebrew: רבי שלמה יצחקי) 22 February 1040 – 13 July 1105, today generally known by the acronym Rashi (Hebrew: רש"י, RAbbi SHlomo Itzhaki), was a medieval French rabbi and author of a comprehensive commentary on the Talmud and commentary on the Tanakh. Acclaimed for his ability to present the basic meaning of the text in a concise and lucid fashion, Rashi appeals to both learned scholars and beginner students, and his works remain a centerpiece of contemporary Jewish study.

What is the sin/violation would have made Judah an outcast in two worlds?
What are other ways we might look at 'the world to come' or 'the Days of Moshiach' besides an afterlife?
How might we become an outcast in two world's today? (whether we believe in a 'world to come' or not)
