Dantes makes vengeance as the meaning of his life. He spent his imprisonment in planning how to garner justice. Determination and willingness to learn are the keys for him to succeed. But then he did not hold the laws by his hands. What he did makes him a just and not a vengeful.
Faith makes him alive, and love makes him going. " Dont let vengeance be the center of your life, because when you are done revenging, your living will be meaningless. Let God be the center of your life, with him you will achieve justice", that is what Dantes taught me.
