Feel Right
          "You cannot do wrong and feel right. It is Impossible."
                                   -Ezra T. Benson
A girl is being bullied, you notice and you try to decide whether to help her out or just walk away... but you choose the wrong and decide to walk away! You obviously did wrong and I'm pretty sure you don't feel good nor right about yourself at all.
What this is basically trying to tell you is that it is impossible to do something wrong and feel good about yourself  and if someone did bad and told you they felt good they are lying to you!!!
