“Empire” is a dirty word. Considering the behavior of many empires, that is not unreasonable. But empire is also simply a description of a condition, many times unplanned and rarely intended. It is a condition that arises from a massive imbalance of power. Indeed, the empires created on purpose, such as Napoleonic France and Nazi Germany, have rarely lasted. Most empires do not plan to become one. They become one and then realize what they are. Sometimes they do not realize what they are for a long time, and that failure to see reality can have massive consequences.
