Buddhism is about training the mind
Buddha said that human beings are sometimes a little too much for their desires and they are a little too much selfish. And they don’t have compassion for other sentient beings or creatures like fish, like chickens, or other animals because they eat them too much. And naturally, these animals have a lot of fears when they see human beings because of our habitual tendency, our aggressiveness. I think it is true that we have a lot of fear to the so-called demons or beings that eat flesh of humans.
