Good is law and order abided by in conjunction with love, compassion, mercy and forgiveness.
Without law, anything goes, and it is survival of the fittest. Savage brutes can get away with whatever they want without fear, but those who are weaker must fear constantly.
That is a common misconception. Altruism, empathy, cooperation, all this is not limited to humans and is observed among animals without the need for human laws. That is because "the fittest" doesn't mean the strongest and nature isn't a shooter game.
