This isn't how I think of morality. Im mostly just being pedantic here but it stuck out to me in a weird way so here's an internet comment with my thought.
You can do whatever you think is right for you and I have no judgement for you either way, I just don't personally use morality to describe this kind of situation.
I think I agree with some of your underlying sentiment about the normal work and human experience being ruthless and cruel, and I understand the foolishness and danger in treating bad people like they are good by deciding to do that is your moral decision it isn't someone outside or morality in some way.
Morality is only really tested when it isn't the easy or most profitable way.
