"You cannot do wrong and feel right. It is impossible"
                                                                                 - Ezra T. Benson

Not necessarily people have different opinions about things and whats done or how it can be done.
People say that if you kill someone then your not doing the right thing, but what if that person was attacking you would you still be wrong? I'm not saying Ezra is wrong but it doesn't have to be only that. Some people do the right thing but feel bad about because it can be their friend or family.
