hmmm. The part that does not make sense is that what we do to others we also do to ourselves. So being cruel to others will cause cruelty to ourselves. i suppose these entities do not believe this which means they are under the sway of avidya and maya.
There have been livign examples of such demonic creatures. One of them is Stalin., Even more than Hitler.
He was cruel to millions of people, his own people. He cultivated Revenge. He was a master of deception. He never had any thoughts about cruelties to himself. Nobody or nothing could be cruel to him because he was totally heartless.
Hard to understand these creatures.
