The Roman Emperor Nero, a monster born from the marriage of his uncle and his niece, was greatly inspired when he saw his mother killing his father when he was a child. As an adult, he became bloodthirsty. In order to seize power, he first He scuttled his mother's boat and sent warriors to hunt her down because she was still alive. He stabbed his pregnant wife to death. In addition to squandering and indiscriminate killing, he suddenly burned down the entire Rome out of nowhere. The fire continued for days and countless people died, but he stood on the balcony and laughed. As for the cause of the arson, there is no accurate explanation yet. Probably it can only be attributed to "not being mentally normal". There have also been great devastations caused by wars in the East, but such inexplicable acts of destruction are probably rare to find even in the history of the world.
