"You can't be right by doing wrong; you can't be wrong by doing right"- Thomas S. Monson

  What this quote is saying if you're doing something wrong, it can't be right. If you do something right, it can't be wrong. I think a good example for the first is part is when someone wants to protect a friend or family of his, so he does something drastic as in something bad, he is not doing right, he is doing something bad.
