You forgot one category. Those who actually don't and have never stolen because they had a time in their life where everything they owned was destroyed, so they don't want others to go through the same thing.
I've never stolen anything, and the only times I've ever downloaded music off the internet was when I planned to go out and buy the album myself, which I did (the only two times I've done that were with Dragonforce's 4th CD, and Kamelot's live CD, One Cold Winter's Night). My reasoning for this is because I know that if I were to create music, I wouldn't want people illegally obtaining it while I become poorer and poorer.
Sorry FrozenPopo, if you wanna try using logic, you have to realize there is an exception to everything
