When is Anger a Mortal Sin?

[PMV]

Although I try hard to avoid mortal sin, I always become frustrated each time I get angry, unsure of whether I am still in a state of grace or not. This has had me confused for a while. Will you please explain to me when it is and is not a mortal sin to be angry?

Try this part of the CCC:

2302 By recalling the commandment, “You shall not kill,” our Lord asked for peace of heart and denounced murderous anger and hatred as immoral.

Anger is a desire for revenge. “To desire vengeance in order to do evil to someone who should be punished is illicit,” but it is praiseworthy to impose restitution “to correct vices and maintain justice.” If anger reaches the point of a deliberate desire to kill or seriously wound a neighbor, it is gravely against charity; it is a mortal sin. The Lord says, “Everyone who is angry with his brother shall be liable to judgment.”
