Control

Some humans need to have control over other humans. The least powerful of these humans can only control their spouse, or their children, or the humans in their immediate surroundings. Some humans, however, make it a career of controlling as many other humans as they possibly can. These humans become police officers or politicians. Like all of the false things in life that humans think will bring them happiness, more and more is always required. As everyone in that situation finds, more money, more control, or more things, never brings them the happiness that they expect it will.

Sadly, there are more who want to be controlled. I think Annie Lennox said it best with that Eurythmics song, Sweet Dreams. It sounds like it really refers to the Sado Masochism mentality. Beyond the realm of sexual fetishes though, comes the people who need a more structured control over masses, not just one human. These humans have a disorder, but seeing how society views personalities now, I imagine we can't refer to that as a disorder. They are just..."different". If they crave the domination of humans, then we just have to accept that.

For politicians who want to control society simply for their own wealth, we can class that as a mental illness. We can group it with the addictions that are commonly treated. They only order people to be harmed and imprisoned to advance their careers and earn them money. For the police who are there to "serve and protect", it is a sign of very poor character to be harming the non-violent individuals just because they choose to.
