TSJ most valuable character is repay those who hate him and want to destroy him not with more hatred but with forgiveness. it is not like he is a saint - not angry and sorrowful but he choose to let go. And that is why precisely in the end he has XY.
people who cant let go of negativity whether it is hatred, pain, hurt, betrayal, power, status or wealth will always be missing something. Cause heaven is fair, u lost something you will gain something in return. so if TSJ cant let go of hate, TSJ will never have any room to love and be loved by XY in return.
