Anger may be justified or unjustified. God’s anger is always justified, based on principle and in His consistence of upholding truth. God’s wrath is against all unrighteousness.
“You are of purer eyes than to see evil and cannot look at wrong. . .” Habakkuk 1:13
However, man’s anger may only be proper if it is based on principle. We are commanded to abhor what is wicked.
“Let love be genuine.Abhor what is evil; hold fast to what is good.” Romans 12:9
Man’s anger is more often unjustified and uncontrolled. Unjustified anger has led many persons to greater sin.
