Hmmm...Gogas, it's really up to you. Maybe, you MADE the bomb and watched your friend set it? That would make you SLIGHTLY less villainous, and more along the lines of, "Gosh, this is fun building stuff and running around getting rich from my friends and it's not like my actions have consequences" than "Mwah-ha-ha-ha! I like blowing stuff up and setting things on fire!" Or not...I think at this point, it's up to YOU how tortured you'd like to make your character.
