What do you think real soldiers see? Picnics?
Most soldiers all around the world saw some fucked up shit ordered by gloryhound or sociopathic higher ups and they kept their mouths shut.
Why? Because it wouldn't solve anything and at most there would be more victimized people. You know that even in our society there's just some people who are untouchable for some fucked up reason and raising your word is just asking to get fucked in the ass, with perhaps your family and friends being targeted as well just so everyone knows their lesson.
There are times to fight and then there are others when you come and make the best of a bad situation.
Hell, at the end of Egghead we saw a Vice-admiral get fucked just because he raised a legitimate question. Is he evil?
Sorry for rambling, but honestly I'm getting tired of seeing you constantly repeating the same autistic take that all marines must be evil. It was funny at first, I'll give you that.
One Piece has some goofy shit, but the portrayal of the marines is actually one of the points that's actually handled with quite a bit of nuance, and I still don't understand how all that just flies over your head.
