Not to mess with the nest but the chinese started the massacres with the Zhao kingdom genocide, the main precursor/ancestor to the mongolian steppe nomads which became nomads in small-ish part due to the persecution and the literal worship these areas have for their ancestors led to bad blood for centuries, boiling the pot for mass-scale butt revenge that spawned an empire.
Also the classical Aztecs were already overthrown when the spaniards came, you are thinking of the Mexicas, which were the chimp-tier lower strata of society (including tons of small foot soldiers and non-nobility elite warriors) that forcibly expelled the older rule, hence why Cortez got overwhelming support by loyalists when he managed to explain his route of action. Aztecs were butchers but they were more about making taxed-to-hell satellite states with an aligned leader on helm, also never attacked the Northern tribes even when they knew about their trade routes and exotic goods.
You are not all that wrong, just wanted to point small details, even when your examples were asking for it. Although half of the injuns in the Mississippi area and Southwest were pacific (plus an entire age behind to be a continental rival) and had no business being executed by power-drunk brits, see the Crow tribe for example, always helped the colony rule and were vanished for being red in the Manifest Destiny days. These are cromwellian anglos we are talking about
While it is true Europeans have spilled some beans along the way, i have no doubt somebody else would've done the same if they were in a similar situation some other day, it just happened to be some moors searching for their redemption by their perceived homeland and later a couple of brits led by someone who might or might not have been a brit. Vikings didn't bother with some Athapascan/Inuit archers, Macedonians didn't want none with black jungle demons, supposedly the chinese didn't either with a bunch of Cahitan.
