Cynically, it’s not who is actually responsible and by how much, it’s who is forced to take the blame.
Arguably the German nation/culture has done this. At least in large part. Not sure any cultural repentance would ever be enough though.
I also feel like there is in Canada at least a growing understanding of the horrors of colonization and attempted genocide and assimilation against First Nations here. Whether that ultimately leads to reconciliation and a better path forward is hard to say.
There's matters of degrees. And this is just one or two steps away from full autonomous murder.
Reminds me of this section Frank Herbert's God Emperor of Dune:
... She would carry with her forever afterward the clear sights and sounds and smells. The seeking machines would be there, the smell of blood and entrails, the cowering humans in their burrows, aware only that they could not escape . . . while all the time the mechanical movement approached, nearer and nearer and nearer ...louder...louder!
...like the terrible machines of that apocalyptic vision, the predator could follow any creature who left tracks.*
