Rape is such a hard to understand topic. I was in an abusive relationship many years ago, and it resulted in me getting raped. It took me up until last year, about 3 years after the incident, to even be able to comprehend what had happened to me and why. Part of what made it so confusing is that it wasn't a violent act done in a back alley by a complete stranger. It was more of a misunderstanding. Even to this day, I know for a fact that he does not see himself as a rapist or that he could even see why I would see it as such a personal invasion. In this situation, the best "punishment" per say would just be some good ol' understanding. Maybe some counseling and rehabilitation for him so that he can see that what he did was wrong and that it shouldn't happen again. Jail will do nothing. He won't feel remorse because he thinks he did nothing wrong. Killing him is just over the top. Again, he can't feel remorse. The whole idea of "punishment" is to get somebody to learn from their actions. They can't learn if they're dead.
