I can think of a billions ways that I've embarassed myself from drinking too much, or even tripping to much for that matter. But as for straight up embarassing? Probably that time when I went to school and all the kids were laughing at me and I realized I was naked. Oh snap, wait that was a dream. Actually it wasnt even my dream, I think I saw that on television
absolutely and it would be a list. (I am assuming moral consequences, and consequences in terms of altering reality are both included in a blanket "no")
I think I meant something more along the lines of law. And maybe no one would find out. They'd just put the victim on a missing persons list. Moral consequences is probably the main objective of the question.
Assuming my conscience would be clear I'd pick this guy in my geography class. He's fat, he's thick, doesn't know how to pull his trousers up and somewhere along the line dreamt up the fact that he's cool. EDIT: With moral consequences then I'd not do it. Bad karma dudeee...
Personally, I MIGHT be able to kill, without consequence, a certain person who has put me through so many dark and terrible places. After so many years of fearing and hating the very core of this person, I have learned to have hardly any empathy for them. It's scary to think that I'm capable of so much violence and anger, but even the best of us can be pushed to our pacifist limits.
