Rules of the pure-hearted.

Killing- A good person can't kill another good person in a training match. In the Budokai, they can. Good people can attack and kill evil people, though going on a killing spree of all the evil people is not actually good.

Protecting Planets- This is done basically the same as taking planets over. You openly claim a planet as your protectorate. If anyone challenges the group protecting the planet, they fight. If the good group loses the planet becomes property of the opposing group.

If you choose to be good, you are expected to act that way.

As for those of the pure hearted, that is all of the rules
