As for hatred, I don't know that people "love" it. People just have a need to be defiant and rebellious.
As for power, people are sometimes control freaks. They need to be in control of all situations. This has to do with how they were treated as a child. If they were beaten, or bullied, they'd like to rise up and become the beater or the bully.
Hope that helps!
