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
you should look into the relationship between deer and wolves in the inter-mountain west in north america. in particular the case studies of the removal and later re-introduction of wolves to yellowstone. there's some interesting work being done tracking degenerative conditions among deer populations that may be tied to the removal of predator animals from the region. hunting is popular in the region, so its not like humans are doing the job properly either.
its interesting to think about and it upsets dogmatic vegans so win-win. this view leads me towards eating mostly vegetarian, so its not like i'm diametrically opposed to veganism or super into meat eating. it just doesn't seem coherent to me to draw this special distinction between humans and animals. a solid philosophical system in my opinion should be able to address all inter-species relationships in some way, otherwise it cannot grapple with concepts like homeostasis effectively.
