I don't usually use 'evil' to describe things but I don't know any other word to describe settler states and their tendency to massacre and torment people they stole their land from and gleefully brag about all the horrific atrocities they've committed/want to commit. Never before have I seen a group people that take more joy in the suffering of others than the kinds of people that want to wipe out entire societies and claim their land for their own.
This is the kinda shit where if you write villains that act exactly like this people will slam you for bad or unrealistic writing, but no, it would actually be perfectly in line with reality all things considered.
EDIT: ps I know me not good at writing things. Wish I can write my thoughts on this better, but I can't really get it into right now
I thought about that while writing it, but I couldn't quite figure out a way to complete that thought and articulate it. Because while it's true that they're more readily accepted into the imperial core than their victims, they're still not guaranteed the level of comfort and security they have, they're not assured employment or stable housing, and if their assets are all tied up in land or share ownership of companies in the settler state they could be quite destitute. They don't have it as bad as other refugees or immigrants, obviously, but that sort of uprooting and chaos is still something scary and threatening. So I left it as-is, since that bit is also more a stream-of-consciousness expression of settler fears than an exhaustive description of what relocating them back into the imperial core would entail.
