You're looking at the picture and not what it represents. You should know better than this.
Atrocities happen in war, that's a given. Even non-warfare massacres are their own thing, ethnic/other heat-of-the-moment(comparatively) things that will either burn out quickly with the anger of the aggressor or with ongoing occasional flare-ups and vendettas.
Kidnapping, rape, theft, beatings, imprisonment, mutilations, "breeding"(what would later come to be called eugenics), medical experimentation, forced re-education and brainwashing, family erasure, spiritual erasure, linguistic erasure, religious support of all the prior as spiritual policy, across nations, an entire continent in chorus saying "yeah, there's money to be made from this system and God approves", then cut out religion as the middleman and made money their god to streamline the entire operation, with all the occasional tinkering and operational changes that need to be made to maintain and perfect those systems to the tastes of the various nations, all the effort and work of generations, and only "end" that system - officially - not because of any change of conscience nor policy, but because the optics were bad for business. (If you need evidence of that last sentence, ask yourself about sincere apologies and restitution. None. The chosen course is to pretend it never happened, minimize the need to look at it and see it for what it is, and hope that people forget enough to let assimilation do it's work.)
The Jewish people's experience in Egypt comes close, but no African banking families profited from their enslavement nor funded the building of transports to ferry them about. The treatment of native tribes in this half of the world also comes close, but they were never an economic base. What's happening with the Uighur people now ticks off a few boxes, but the timeline obviously doesn't match.
I challenge you to find me a name that encompasses all that over four and a half centuries, that spans an entire hemisphere. You won't. None of this was inflamed passions, not anger nor revenge nor vengeance. This is wickedness and evil on a scale not seen anywhere else on the planet. Nothing less.
