I am disquieted at the thought of an angry Jesus. But the Bible was not written with my sensibilities and my concerns in mind.
Anger is a human affect which becomes destructive in most of us because few of us, if any, can master it. Rather, it masters us.
I think that Giotto does a great job in painting an angry Jesus with a composed demeanour.
The Lord’s face radiates anger, not a destructive rage let loose.
