Yes, because he still a humane being. One should never allow unforgiveness to be a part of one's life. Let kindness be your life's mission. Supposedly Buddha said : Let kindness be your religion. And in the Wiccan Rede it states: An (If, in modern English) it harm none, do what you want.

Yes as that would be me.
