I believe the word often used to describe a person like you just did is sociopath. I may be wrong on the word, but behavior like what you describe is classic, the basic justification for all criminal, and immoral acts. "I can do what ever I want, because I want, and I'm ok with that" is the rule of the jungle, is it not?
I left a reply to this last night and it's gone now; not sure why it was deleted.
You left out the part where the one ignoring the rule is okay with accepting the consequences. There is a proud history of civil disobedience in this country, and I find your use of the word "sociopath" offensive in this context.
