"You cannot do wrong and feel right. It is impossible."
I think this quote means that we can't make a lie and feel right because if we lie, we might hurt other people and friends. When we do something wrong , it not right to feel right when we did something bad. When we see other people do something wrong and you want to do it too, it will make you feel bad of what you did and choose the wrong. Don't let your freedom fail and choose the right.
 When someone told you to do something they lie, don't choose to do what they told you because it might hurt you or get you in trouble.
