This is something I've struggled with quite a bit...at first I didn't care. I don't think anyone really should care. It's really a way to vent some of your more devious desires. But, I have stopped doing crimes in my own lucid dreams for my own personal reasons. I think it really comes down to each person. (I mean...if you're doing crimes in your dream and it makes you want to actually do them in real life...then that's a problem. Not that that's the reason I stopped, but I'm just saying...)
