My brother in law and husband have a code in the game where they don't unnecessarily harm or rob women, Native Americans, and black people in the game because "they have it hard enough." They included Mr. Margaret in this due to his likelihood of being LGBTQ in some fashion (at minimum he's a transvestite). They rob everybody else. On my current play through I've gone with trying to get my morality up as high as possible. On my second play through though, I will probably follow their code because I like that. There's still plenty of outlaw stuff to do even if you exclude those categories of people.
