I'm a pirate and a thief and I enjoy it. I guess there's not really much guilt to taking what doesn't belong to you if all it takes is a simple download link; there's no real visible effect that can be seen that you are taking from someone else, especially in the case of file sharing. I'd have more guilt over shoplifting when I was a little kid than downloading anything over the internet.

Not to say I don't ever buy things (I know I really don't like downloading books as it doesn't feel the same) but if stuff like games and so forth can be emulated; or music can be downloaded, then I will more often than not do so.
