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
in other forms of colonialism you can profit from the natives being robbed. Settler colonials however require the natives to die so the claim to their land can be fully realised.
actually they need the natives to have never existed in the first place but the first step to that is to kill them
this was one of the sources of conflict between Britain and America in the run up to the American revolution
This is an extremely important point, and one that is usually swept under the rug in the USian telling of history
to be clear it's not that the British morally objected it's just that the natives were more profitable for Britain than the settlers and Britain did not want the settlers who were a bad investment comparatively to destroy the natives who were profitably exploited in the fur trade
Also the natives were a source of local armies that allowed Britain to relatively cheaply fend of Indian and Spanish claims in America if they were kept on side and very expensive to fight if they weren't. It's was no small expense to train an army in native suppression in London, equip them and then ship them thousands of miles.

For the settlers however the natives were simply in the way
this led to a conflict of interest in the two colonial groups
Bacon's Rebellion is such highlight of how deep this runs. Literally all lower classes, including slaves, united against the Virginia planter class, just because the Governor wouldn't genocide the Natives.
The private ownership of land is always the material cause. The lower classes of settler colonials always wants to flee their own society because of consolidated land ownership. Same as when early Virginian colonists wanted to run their own tabacco farm instead of share crop. Same as now with Israelis moving to cheaper rents in the West Bank.
