Did. Or, he's not above it, anyway. Sabretooth, I THINK that it was stated (Or hinted at.)that he raped Silver Fox, one of Wolverine's old girlfriends. Crossbones had, at the very least, physically assaulted Diamondback and the Red Skull's daughter. I think that I read that he raped them, but nothing was outright stated in the story. Norman Osborn (Seemingly.) took advantage of Gwen Stacy and Harry's girlfriend Lily (Ugh!), but that wasn't outright rape. The Purple Man is really the only definite one that comes to mind, but the other ones probably did too. I can see The Owl (Depending on how crazy he's being written. He's seemed to have gotten a lot crazier over the years.) maybe doing it, but to my knowledge, he's never done it. I think that The Ultimate Universe might have a decent amount of that. But aside from The Purple Man, no!
Also, is Dr. Light being a rapist even part of the 52 cannon? Heck, does Dr. Light even EXIST anymore?
He showed up in an issue of Justice League during the "Trinity War" storyline, but was unintentionally killed by Superman (Atomica shrank into his brain and triggered his heat vision).
