Why steal a dollar?

So today I was selling cinnamon buns at church for a fundraiser with someone else from the youth group. No one was looking and she says "I think I'm gonna steal one." word for word. I tried to tell her that she was stealing from her own group but she just said "Who cares?" I mean really, it was just a dollar but the morals are screwed up there. She had absolutely no remorse about it and told me to leave her alone, which I did. Is she doing it just for the thrill and rebellion or even to look cool (which I just don't get when people think stealing is cool), or does she honestly want a cinnamon bun that bad and didn't have a dollar on her? Seriously, what's the point in not paying a dollar? It makes you realize that some (and by some I mean a lot of) people enjoy doing something more when it's wrong. Is it because they don't want to feel controlled? More like they already feel controlled. That just leads to the fact that most people are uncomfortable when they can't control something, because they can't work their will or have their way.
