Good Karma.

He knows that he will lose and that he will lose badly. Unfortunately, his bloodline doesn't think that so he is here. If good men don't act, then bad men will get away with their sins. Every possessor of the bloodline of the lion of justice is a good man. So he must act no matter the situation. It is so that Soverick won't get away with his sin. Justice does not sleep, and neither does it get tired.

The moral high ground is very important to those with the bloodline of the lion of Justice. It strengthens them in varying amounts depending on how morally depraved their target is. There is no right or wrong so Good and Evil is relative. The major entity that decides if someone is evil is his bloodline and it does so based on karma. Doing more good than evil gives you positive karma. An evil person has negative karma. They have done more evil than good.
