Are you a vigilant person who stands up for what is right?

I mean, do you take chances by opposing wrongdoers and injustice because it's wrong, regardless of the opposition or risks? For instance, would you oppose your boss if he was doing something illegal or harring you or another colleague at work, even if it means you risking upper management turning against you and possibly retaliation from them. I mean, basically, do sit down and take it, or do you stand up on both feet and push for what's right no matter what?
