One of the reasons why I follow crimes is that I was victimized several times in my life and I always feel for the victims. But that's also the reason why I have to emotionally distance myself.
And this guy is one of the worst out there, I really can't see him as a human being and I know a lot about psychopaths and how their brains are different which turns them into something that looks human but has no human traits at all. He definitely committed more crimes than the ones he was convicted for in my opinion, and even those should be enough, but then there is German law. I hope they can solve at least a few more and realize how dangerous he is and keep him in preventive custody for life after his prison sentence. If he ever gets out again, he will never stop, he can't, his twisted brain wouldn't let him even if he wanted to (not that I think he wants to change though).
