Do not take revenge, my friends, but leave room for God’s wrath, for it is written: “It is mine to avenge; I will repay,”says the Lord. On the contrary:
“If your enemy is hungry, feed him; if he is thirsty, give him something to drink. In doing this, you will heap burning coals on his head.”
Do not be overcome by evil, but overcome evil with good.

The Bible

Romans 12:19-21
