Class discussion - modern lit

Yesterday we had a really good conversation about all the creepy people in this world. It really makes me wonder if people are really born that way or if they were made to be that way.. We talked about this man in Austria that had kept his daughter in the basement for over 10 years. The wife/mother said that she had no idea but I think she's full of crap. If your child went missing all of a sudden, why wouldn't you call the police? Anywho, the guy raped his daughter multiple times and she had 7 children by him. Which is absolutely repulsive. We also looked in our area for registered sex offenders and honestly, it scares me to know that there are so many in our area. People are sick.. I just don't know why. We also talked about this man and woman that filmed kids that they wanted to take. They ended up taking this girl and keeping her in a tent in the backyard. She also had two kids by the man. The man was already on probation or parole (not sure what the difference is...?) for sexual stuff. Every time the officer would come over to search his house, for some reason, they'd never check the back. Which I really hope they got fired for that because that's their job and they could've saved her. I like topics like this because they're really interesting. I also like it because everyone has different opinions and its cool to see what everyone else thinks.
