I am sorry. I have not said it is impossible to not be angry at people.
I have said anger is an appropriate response in certain circumstances.
I think you are extending legalism into emotional flare-ups?
Is it a sin for a parent to be angry with their child?
Is it a sin for a teacher to be angry with a pupil?
Is it a sin for a husband to be angry with their wife or the wife with their husband?
Is it a sin for a teacher to be angry with a pupil?
Is it a sin for a husband to be angry with their wife or the wife with their husband?
You appear to be claiming this is murder? Please help me understand you reference points.
If you do not forgive, you will not be forgiven.
The man who has his debt forgiven by God who then demands payment from someone else instead of forgiving their debt will be thrown into prison until he pays the last farthing.
I say to you if you have anger in your heart without cause at your brother, you are guilty of murder and the judgement.
All of those reference points should make a man cry out to God to forgive him of his sins. They should cause him to hunger for true righteousness in his inner man. But if he cannot see his murder, he will not repent and ask for forgiveness. He will just claim to have always followed the law to not murder all of his life. (Which is legalism and is seeing the letter of the law but not the spirit.)
