In fact, this whole time, there's a lot of relatives being killed, people who might threaten the emperor being killed. And that's just talking about the Romans themselves. They're constantly fighting the Germanic tribes and groups in the Middle East and taking more and more and more territory. These are extremely bloody things. They're constantly enslaving people. The Roman Empire, sometimes it looks like this neat, clean, idealistic thing, but there was a lot of enslaving of people, destroying of towns, killing people out of paranoia or really just out of the joy of killing if you take the case of Caligula or Nero. So then you have the Flavian dynasty.
