How do i delete this guy from my friend list?

I'll admit, it was very decent of you to accept him when others don't... I won't deny you that much. However, here's a catch, there's a limit to such things. As a christian i would say "If a man asks you to walk with him a mile, go with him the second"; yet even then there are some limits.I would advise at best, that you maintain your verbal friendship with him. No matter how rare or uncommon your conversations are, it may help him to some extent, this means a normal conversation, not necessarily to correct his faults. He seems to crave some kind of attention, and talking to him i understand isn't an option, however, listening may be.... as his for his Facebook, i would delete his profile.."unfriend" him.... it may ultimately be your undoing... sounds double standard-ish, but better to keep your online reputation intact than to have both social and online reputation broken....
