1) Yes, absolutely. If you've committed unspeakable acts against people, then you should be punished in life as well as death. Even if they evade justice in this life, they'll get what they deserve in the next.
2) NO! What's to stop your child from thinking it's OK to go do it for money because it's legal so that makes it OK? It's wrong, and no woman should ever have to sell their body for money. Another stain on the human condition.
3)Absolutely yes. And yes again to them having some kind of physical punishment. If the punishment was so steep, they would think twice before raping, abusing of any kind. It's in their blood to do it anyway, so f*ck em.
