I'm afraid I'm going to get roasted for this, but he sounds like a normal guy (obviously, i know that he's not) and he's attractive and had a good job etc. Why in the world would he destroy his own life via destroying a sweet innocent young woman's life? My point is that he had a life too, why did he DO this??!!!
My sister in law is a criminal psychologist with PHD and she says that many of them don't want to be rehabilitated. She worked with prisoners that were pedophiles. She said that as their sentencing came to an end, many would admit that they would most likely do it again, but they still set them free??!!
He did it because he is a sociopath. He does not care about who he hurts. He just wants to satisfy himself. These types of people do not feel happiness like a normal human being. Having a good job is not enough.
