I guess it's because the Napoleonic wars were so bloody relatively speaking. The proportion of the European population that died as a result of them is in the same ballpark* as the proportion that died as a result of WW2. The number of dead bodies is not an unreasonable metric for measuring the actions of "aggressive conquerors". * difficult to get precise figures but I estimate within a multiple of 2 or 3
