Honestly, I'm sorta appalled at the forum's reaction to Iban. Yes, he may have done things that are less than normal, but that is really something you can't blame him for. These things happen, whether it be through traumatic experiences, or just natural cause alone.
I would befriend him, even if it meant giving up my dignity to this forum. This guy should see a professional, and maybe he could be melded into a fairly normal guy.
