Humanity part 2

Vampires have a problem with losing humanity because of their necessity to live off them for a very very long time (well if they're lucky). When vampires completely lose their humanity it can be very very bad for people. In fact if you are a person and you find a vampire who's lost it's humanity count yourself dead. A few signs a vampire might be losing it.
1 - you start viewing human as cattle.
2 - If you don't need to sleep in a coffin and you sudden get rid of your comfortable bed to sleep in a little box.
3 - If you start thinking about taking over the world and bending it to your will. (this might also mean you are an evil genius)
4 - If the idea of using human heads as soft balls no longer bothers you.
I'm sure there are many many more things that warn you of your fall into darkness as a vampire. But I figured this was a good start.
