D10: Why is that person/creature doing evil stuff?

I came across this post a while back and found it quite in line with how I wanted my games to run.  I decided to make a convenient table of the main categories of villain motivations, to ensure villains have a nice variety of motivations.  

Anyway here it is:

D10: Why is that person/creature doing evil stuff?

1. They believe they are acting in self-defense
2. They believe it's for the greater good
3. Self-interest, they believe their needs matter more than other's do
4. They believe other people will hurt them if they don’t assert dominance first
5. To get something they desperately need
6. Pure sadism
7. They're just totally numb to suffering and don't think about what they're doing
8. Their senses are warped and they don't accurately perceive what they are doing
9. They are in pain and lashing out randomly
10. Roll twice and combine

Please comment if you can think of any more options to add to the list.
