Immoralism finds no right and wrong in the universe: cats eat birds and fire burns houses just because that's what they are. It’s the same with humans, according to immoralism, so rules of right and wrong are made up and pointless.
Believers in immoralism, such as the philosopher Nietzsche, consider rules or laws about right and wrong to be little more than a human invention created so that people could feel safe — and control others. According to immoralism, if you don’t want to be controlled, then don’t accept or follow those rules. Just do whatever comes naturally — but try to make sure you’re stronger than everybody else, or someone stronger than you may take you down.
