Where did they ever showed the good side of the empire? Also they already said that they made Zenos that way because people liked Gaius even though SE never intended for him to be seen that way. So no even Gaius, the one that a lot of people like because they can agree with his ideas, was not meant to be seen that positive. Also if you go down to it, he did a lot of things for the good of Garlemald (drop a meteor on Eorzea and there is nothing to rule over, make a mass murder poison, and there are no people left to rule over. Nothing of this screams: I find it morally wrong to do) And lets not forget that he was the one that gave the order to raid the base of the scions and as someone that knows his followers he should have known that they would show no mercy. Thus he was fine with countless people being killed. If they were part of a city state or a rebellion against Garlemald then I could have understood them but they were neutral and only tried to find a solution against the primals. There was no reason to kill all of those people (and even that poor sylph). Also he more than once showed that he saw Eorzea and their people as less. Savages is a word that Garlemald loves to use a lot.
Before ARR: Conquering the world because everyone should be under their rule, kill Middy and break the seal of the lake thus making it easier to summon primals, wanted to drop a moon on Eorzea (and where only stopped because of the old WoLs and the old man). Bahamut freeing itself also killed countless of people and threw the continent back some years and even today people still feel the consequences of this catastrophe. If they would have succeeded with their moon droping another true calamity would have been done and thus a whole shard would have been destroyed (thus billions of lives lost), conquered part of Eorzea and threw lots of people into poverty thanks to that.
ARR: Slyphs summoned Ramuh because Garlean soldiers destroyed the forest they live in and they are afraid for their lifes. Raid of the scion base, killing countless of people because of that. Are saying that they want to kill echo users for this ability. Working together with the Ascians and are using Ultima, a weapon of mass destruction, to make the city states surrender. The destructions of Bahamuts rage are still felt around Eorzea and is the reason for a lot of conflicts between Eorzea and the wild tribes. (Sahagin losing their breeding ground thanks to that)
HW: Showing their wish that they want to kill of all wild tribes just because there is a possibility that they could summon a primal thus wanting to commit Genocide. (There is nothing that much shown about the empire in HW that I remember but the only good deed someone did was the sacrifice of Regula against Zurvan)
So not to be pedantic but could you give some major examples of the good side of the empire in ARR and HW? Because in the end when I look at it, I never saw true good things from then and they are the indirect and direct reasons for a lot of problems in Eorzea.
Also not to sound mean but I am from Germany so no need to teach me about that part of our history. And I already wrote that I believe that Garlemald itself might have a good amount of innocent citizens but that does not change my opinion that the government itself needs to change otherwise I cant see how we would truly work together.
About Third Reich: Yes some might have not known about all the bad stuff that was going on but people cant just go around and say that they did not know about the imprisonment of Jews and some villages are even near those killing camps so nobody can tell me that they did not know something. Also there were probably a lot of people that are just simply racists and at the very beginning people also loved the though of war because they felt that they had to pay too much after the first world war. In the end you will always have a part of people that are really behind the dictator and love to do everything for them, you have part that believes that nothing is wrong and that go on their life until they see what truly happened (which is probably not the majority of people) and you will have people that know whats happening but are too afraid to do anything. And then there will be a part of people that are trying to do something against it.
The side quest Black rose really hit me hard because they really showed the parallels of Garlemald and the Third Reich. In the Third Reich we had a rebellion called White Rose, which were students that were against the regime but the two siblings that lead them were later killed for that. I do believe that Black rose is a hint towards this, especially since it was about experiments on prisoners.
Also lets not forget that pure blood Garleans are blond or white haired. The Third Reich had a belief that blond haired and blue eyed people are the true master race. Also they looked down on other races for being less superior. This happens with Garlemald too. Everyone that is not a pure blood will not get the same rights as them and they even want to kill of the beast man and call people of Eorzea Savages too. There are many parallels to our real life thus I just cant see them as good.
I am not saying that anyone that is a Garlean fan is a bad person or something. There is always that kind of lure to side with the bad guys. But at least right now they are the bad guys and they did a lot of horrible things that at least the current leaders of Eorzea would never do.
Well one could argue that them killing Middy and thus destroying the seal was bad for Hydaelyn. Also even if Nael was a bit crazy, letting a moon fall on any country was something that higher ups needed to give their okay too. If the moon had fallen on Eorzea we would have another true calamity but even just Bahamut must have damaged the land and Hydaelyn a lot. And it created a lot of conflicts which were the reasons for summoning more primals. Also we know of some primals that are summoned because they are afraid of Garlemald.
And I agree with you. Just because they had it bad in the past gives them no right to the things they do today. First they come from a whole different continent so if they wanted to take revenge on those that pushed them back they could have just conquered their continent and be done with it. But like a lot of states in real life, they got greedy with their power and wanted more. They saw how technological advanced they are and thought that everyone not Garleans is bellow them and need their rule. They also showed more than enough in SB that they dont care about the culture of their conquered countries and wanted only one ideal to live on: theirs. They could have gone the way to use their technology in trading thus getting the resources that they are missing, there was no need for war.
And before someone says it, I know that the states in Eorzea area also not free of racism and other stuff. But at least they still try to find better solutions instead of Genocide and other than Ala Mhigo they also never tried to conquer the world.
