Evil empire is the one that lost.
The empires that fell were indeed already warmongering, and dominating their part of the continent due to fighting successful wars and/or alliances. In that sense, it was "only" an empire taking down another. That viewpoint is however just the politics of the history. We can't forget how it affected the people.
I guess it’s a win, but in that case I think the entire concept of the pyrrhic victory needs to be renamed…
