Micah's thoughts at Cinco Torres are sealed when he sees Dutch trying to reassure the gang into going with him. If you noticed this, Micah looks at Dutch with disgust and hatred:
Micah is a scoundrel, a rat, the lowest outlaw of the West, but he doesn't pretend otherwise nor he lies to himself about what he is or what he does. Dutch on the flipside, pretends that he is a hero even though he is just as full of shit as Micah is.
100% agree with this. In Guarma we see a very noticeable shift with Micah and how he views Dutch. We see it in Cinco Torres and the final nail in the coffin (from my point of view at least) is that boat ride back to the US. He finally sees Dutch for who he truly is and it's not the sort of father figure/respected boss ideal of a man that he had been clinging on to.
Dutch is a deeply delusional narcissist, using and discarding everyone like they're nothing under the guise of being the people's hero and to me, he is infinitely worse than Micah because of that.
I say that mostly because I've just finished replaying the mission "My Last Boy" and I barely see any discourse around how absolutely FUCKED it was, what Dutch did to Rains Fall, Eagle Flies, and their people. (Maybe it's because you can't even blame Micah and his "influence" for that one lol)
