If you've befriended and helped a convicted felon who has served his/her time, is repentant, and presumably is on a path to rehabilitation, then that's laudable, even if that person were a murderer. If you've befriended a murderer who is unrepentant, who managed to avoid any real punishment because of his wealth and connections, and who is rumored to still be engaged in the things he was accused of, I'd say that's a huge moral failing on your part.
