I found this list of culprit mindsets at this site. Something to consider. There are some other interesting things to be found, like a name and plot generators, things to use when you have writer’s block.
"You hurt me. Therefore, you deserve to be hurt back."
"I'm not the problem - everyone else is."
"If others don't go along with what I say or want, then they're selfish/hate me."
"I can't trust others to make good decisions."
"If I have this power or advantage, it's because I deserve it and/or was meant to have it/do great things with it."
"I deserve to have it, and anyone who gets in my way is stopping me from getting what I'm entitled to."
"It's okay if I do it because my intentions are pure."
"If my actions hurt people, they deserved it anyway."
"It doesn't concern me. Why should I care?"
"Even if people are hurt, the end results will make up for it."
"You're getting too big for your boots. Someone needs to put you in your place."
"You are a piece of trash and deserve to be treated like it."
"Deep inside, everyone is just like me. I'm just one of the few people who is actually honest about it."
"I am in a position of authority; therefore, unconditional respect is mandatory."
"They have terrible intentions!"
