Well, the bitch did say he "tried" to assault her while "drunk." This makes his crime much lighter because you don't even know if he wanted to rape her or just came on too strong to her due to inebriation. This also makes it more believable that he stayed around (fell asleep drunk) after the act, then forgot all about it.

Maybe that's why the other heroes, excluding spear dood, are acting like dicks but don't outright attack him, instead opting for childish snide remarks. In their eyes, he is a dick that got a little too horny, not a serial rapist.
