broadly there are two ways you can react when a system you are enmeshed with deals you a moral injury: you can acknowledge both that enmeshment and your own culpability and work to atone for that and to halt future harm, or you can work backwards from "but i'm good, i don't do bad things" and set to work making the bad thing Good Actually until you're totally morally disoriented and find yourself allied with the people burning the world.
you always have that choice.
