You talked about how it's better to be the villain, to just do what you want and let others deal with the consequences. Demon Bull King was being cruel at the time. And like with me, there were consequences. You don't need to remind me that it was cruel. I knew what sealing him meant, even if you feel like it was uncalled for.
