It's a problem I discussed a lot with my therapist. And man, do we ever see it in Jesus. Calling the priests and preachers liars. Screaming his frustrations to the crowds. Driving people out of the temple with a whip.
Anger is perhaps the way they most honestly are themselves.
I often say that anger is the source of my creativity, and I mean that. Anger is what gets me off my fat ass and helps me slowly, laboriously, painfully, write or play or act my way through the maple syrup of my own laziness. As if somehow God was dissatisfied with things the way they were and stormed this giant thing into existence. On the other hand, we must look at those whose anger destroyed them. Certainly self-destruction is the other side of anger's coin.
