You are right, I agree. He is good with no evil in him
But to say that destroying/punishing evil is wrong makes no sense.
He is a destroyer and a life giver; both are part of who he is.
If I didn't accept all of him for who he is, I would be creating a false image. He never destroys without good reason, and he never enjoys punishing people--he wants to bless people.
People mostly destroy themselves anyway because they do not want to obey his laws. If you do what is right, you have nothing to fear (Romans 13). I believe his judgments are just and I am glad that he stands for what is right.
