Duke should be allowed to be angry.
I'm not talking about having a temper or snapping sometimes, I'm talking an actual, genuine crash out.
Like when Kate talked to him as if he didn't know just how evil cops could be.
When Damian called him a coward for telling him friends to comply with the cops so that they wouldn't be killed.
When Dick sold him and his friends out to the notoriously corrupt GCPD knowing full well the danger Duke would be in as a Black boy.
How Bruce never actually put his kids in line for their tone deaf behaviour, like sure he loves Duke, but he doesn't really understand what he deals with nor does he make an effort to do so.
And Alfred...anyone who's read WAR knows I don't need to say more than that.
Duke should get angry. He should crash out. He should openly hold a grudge and make them work for forgiveness.
