Anger is one of those things that define us a human being because to me I don't think we have someone that has never get angry before. Anger is Just like every other feelings like happiness, love, and joy.
Even in the Bible God get angry, this shows us that anger is not bad as you think but the truth is that there is always a limit to everything and we must careful when getting angry. Some people let their anger overclouded their judgment and do unspeakable things.
Ephesians 4:26-27
“26 Be ye angry, and sin not: let not the sun go down upon your wrath: 27 Neither give place to the devil.”
You see that Bible verse, is normal to get angry but sin is not, When your anger leads you to destroying something, when is destructive is now a sin. For some people is not as easy as it may sounds because they can't control it but that is why we have to be spirit filled, holy spirit is our comforter, that is why we need to be closer to God to avoid these sins.
Destructive anger can only take you to one place which is hell fire, do not let your be destructive because be it anyway is a sin, as a child of God we can get angry but when we realize it might get out of control, pray about it and leave everything for God because he has better judgment, judgment is not ours.
Thanks for your time.
