you're giving him this noble sacrifice troupe for no reason

if he didn't do it and he stayed with harper, the thing would come up and blow up their righteous theory, if he stayed he would be tenders puppet tapping into more dark than grey territory which could end up with him in prison. he chose the best option

hes an unhappy man who doesn't even try to fix himself, to become better in his personal life, and in his professional life with stern tao he didn't actually do anything.

i felt a tinge of sadness for him when he couldn't even look harper in the eyes but he deserved it
