Beh. People just want to play bad guys. And they are bad. Their answer to deal with Eorzea after the first attempt was "LET'S DROP A FRIKKIN MOON ON THEM". And they would've succeeded, if it didn't end up containing an exploding dragon god of rage. Instead of completely annihilating every last man, woman and child in Eorzea, they simply caused mass destruction on such a scale that in was considered the end of an Astral Era.

Sure. If they took over the world, there might be peace. You would just have do everything those who rule say to do. Which may include being conscripted in their army as cannon fodder, be used as slave labor, or used as "entertainment". Disagree, and maybe if you're lucky, you'll just be killed. If they feel like an example needs to be made, they'll kill your spouse, your children, your parents, and your chocobo. Then burn their bodies and all your property to ashes. THEN kill you. After torturing you. For a few months. In public.

Dunno if you just wanna play a villain (which is fine. Who doesn't like playing the bad guy from time to time), or you honestly don't think that's THAT evil and the end justifies the means(which merits an eye roll you dark, edgy person, you.), but they're practically at Saturday Morning Cartoon levels of villainy. The only way they could be more plainly evil is if they all had mustaches they twirled while plotting, and black capes...



... well, hell. They're halfway there, already.
