Is my head in the total wrong place when I start to think I should do something nice for him this evening so his anger chills out a bit, or is that the total wrong direction
Totally wrong direction.
Do something nice for YOU. Let him be angry. He owns his emotions. You own yours.
As long as you believe his anger will not turn to violence, you are OK. If you have concerns of violence, then your #1 priority is keep you and D safe.
