III. Safeguarding Peace

From The Catechism of the Catholic Church

2302
By recalling the commandment, “You shall not kill,”⁹³ 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.”⁹⁴
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.”⁹⁵
