[Trivial Psychic]

Let's not forget that one of the hottest series of toys on the market today TMNT, which, in celebration of their 30th anniversary, released versions of their figures celebrating their classic Mirage comic appearances. Bear in mind that those comic version of the turtles were far from lovable reptiles we know today, but where in fact a bunch of jerks who smoked, drank, swore, and were not afraid to kill. They were essentially hit men who were trained not necessarily to fight crime, but to kill the Shredder and his followers in a plot of revenge from their rat master.

Other characters who have been in less than favorable situations that would make the average parent cringe if they knew more...
-Venom (Attempted rape/ Eddie Brock / "The Madness")
-Harry Osborn (drug addict)
-Black Cat (raped)
-Marvel's poster boy the last ten years, Iron Man (alcoholic).

Let's not forget the character that Marvel is banking big on next year...Ant Man (alcoholic, domestic violence)

And just curious...Didn't one of Batman's most idolized rogues, The Joker, also rape Barbara Gordon? It's been a while since I've read "The Killing Joke", but I've always interpreted it that it was an act he carried out after shooting her, given the nature of his taunts to Commissioner Gordon. The fact that I wouldn't put it beyond Frank Miller for him to actually intend for the character to do such a despicable thing also rings out in my mind.
