Good and evil are the friction necessary for conscious evolution.
"I do not understand what I do. For what I want to do I do not do, but what I hate I do. And if I do what I do not want to do, I agree that the law is good. As it is, it is no longer I myself who do it, but it is sin living in me. For I know that good itself does not dwell in me, that is, in my sinful nature.[a] For I have the desire to do what is good, but I cannot carry it out. For I do not do the good I want to do, but the evil I do not want to do—this I keep on doing. Now if I do what I do not want to do, it is no longer I who do it, but it is sin living in me that does it."
"Let him who is without sin cast the first stone"
“You are in prison. If you wish to get out of prison, the first thing you must do is realize that you are in prison. If you think you are free, you can't escape.”
