Timshel

Timshel means "thou mayest". Thou mayest, meaning that people have to choice between good and evil. This choice defines the meaning of being a human. It means that in no matter what situation, even at the worst of times a human has the great choice to save themselves. This connects to Cain and Abel in the sense that Cain, even though was damned with the mark, God still decided to save him. Even though cursed, theres always a forgiving place.
