I know people unfortunatly in both situations. I think it depends on who that person is to you (the rapist). For e.g. If it was a husband, a son, a brother. It may be easier to forgive for some people.
Or if the victim was related to that person or they knew them well then it might be harder to forgive you for hurting someone close to them.
Or it could be in general, where the person did not know either of you.

In my opinion as I know people that have been in both situations I have to say to watch it ruin the victim's life as it did, I don't have any thoughts or time for such a person who could do that to a person and the people around them.
As for saying if I would like for them to either be sentenced for capital punishment or the rest of there life in jail. Well I wouldn't be able to decide without really thinking about it because in one way I don't believe that a person should be responsible for sentencing someone to death but on the other hand whats the point in spending taxes on someone who is just going to get the treatment in the jails they get these days and die in there anyway.
