Many of the Roman citizens believe that Nero did it intentionally to clear out space for a palace. Significant number of Romans died in that fire. He killed a ton of people, including his mother. He's maybe most famous for persecuting Christians. There are some accounts that he would dip them in oil and set them on fire in his garden, just as a source of light. So these people, you know, just to say that they were insane, or demented, or sick, you know, normally I try to avoid making any judgment on some of these historical figures. But both Caligula and Nero, if we believe the accounts that we get from that period and that shortly after that period, were not, by any stretch of the imagination, good people.
