Had to read the next paragraph to know what you were trying to say.

Suggestion:

.... Wouldnt you?

If you think about it, you acted poorly or even hurt them with your contempt, because you turned away from their hummanity. Couldnt it be possible that they did the same when they hurt their victims?

Why is that that when they turn away, it means they are bad, and when you turn away it means you are good? Is it only because you can tell yourself that they are a bad person?

** I changed the you/they here. Also understand the complexity of writing your book as I'm making suggestions. Hope you get the intention of the suggestion.. not claiming it fixes the issue.

The issue I am noticing is that here there was a big jump, and being more explicit as to what is happening would be helpful.

On the other hand of what? - makes it confusing. Can start with "you already knew this would be the likely outcome"

I'm adding comments as to how to make it explicit what you are pointing out.

suggestion: But notice how your contempt creates the self-justifying reaction in them that now gives you proof that they are irredeemable.

Made them feel more justified - of their wrong doing?? made the make excuses for their wrong actions perhaps? -- this sentence is making me guess what you mean.

And the sentence under it assumes that as a reader I answered: hope them feel more justified.

Suggestions: And how do they read? does I make remorse easier? Or does it make them double down in their actions, and justify themselves?

Some part of you knows that contempt will turn them away deeper (maybe giving away too much).. or.. that contempt will further antagonize and prevent them from seeing their wrong doing.
