Yeah, its disturbing and disgusting.
I knew a girl though my group, and she wrote letters to her dad. She was trying to him to confess to raping her her whole life, and she shared the correspondences with me.
It was disturbing. In one letter she came flat out and described some of rapes and attacked him. He responded by telling her he was glad to hear from her, and told her how happy he was. She was hysterical after reading it. She was never able to press charges with the letters as evidence.
He seemed like a psychopath and couldn't admit what he did, but this guy did admit to raping his daughter and he got away with it. If he wants to hurt her more, he can rub the fact that he is free in her face..
I don't hesitate to think the guy is a psychopath and feels no remorse or shame. I wouldn't put it past him to emotionally abuse and degrade his daughter with the fact he was never punished for raping her.
