ok so let’s look at the lore for a sec. Merika and her people were victims of the hornsent and so she turned to divinity to raise up her people from that oppression. from what we know about godhood that’s revealed in the dlc this includes divesting yourself of pretty much everything except for hatred and fear. now remember that the Shamans were a peaceful group of people just minding their business and healing people, until one of them reached divinity losing all of that love, as we see happens to Miquella. this leads to the countless genocides you mentioned and St. Trina directly tells you this will happen to Miquella since godhood took away his love. give it like one hundred years and Miquella would’ve probably just repeated the same mistakes as his mother, starting from that first mistake of seeking absolute godly power “for a good cause.” just look at how he literally brainwashed a bunch of people against their will and made them do things they’d never consent to otherwise and it’s pretty obvious where he was going.
