Look around in nature. Look at everything you have ever seen in nature and know to be true.
In nature, among all living creatures, on land and in the sea, the strongest devour the weakest. The weakest, most vulnerable become the victims of the stronger. We also call it “bullying”.
Have you ever been around chickens, for example. In a flock of chickens, the stronger chickens will always choose a runt. They will harass the runt, attack it and kill it. This abusive behavior is repeated at all levels of life, all animals, even among humans. Human history is full of similar examples. Just look at the violence in Mexico and in the Middle East, or the abuse of children or of women.
