Given his youth, and knowing myself at his age, I would go with "demented youth", although I would replace "demented" with "disillusioned youth". Torah teaches us to judge favorably. I don't know Chaim, but I imagine as a Jew he is open-minded about authentic teshuvah. In the absence of teshuvah, ostracization is prudent.
Issac, Jacob/Israel, and Judah, all transgressed, and made amends.
Judah's redemption in front of Joseph is the reason Judaism is called such. I believe the incident is when he put his Father's needs, emotions and life before his own, regardless of whatever cost he may bear; "selling Benjamin into slavery as we did our brother Joseph would surely kill our father, today's consequences are ours to bear not his", or something similar, I am not quoting a direct text. Are we all not lessor than the Patriarchs?
My standards for teshuvah are very high, I imagine Chaim's may be as well.
