"Hey Vito, don't kill him--just rough him up, and while your at it Vito wear a condom when you're out on the town--it's self defense you know!"
From NCR:
Traditionally, confessors and pastors have long been permitted to counsel a "lesser evil" to prevent greater harm. For example, if a mob boss tells a priest he intends to kill an enemy, and if the mob boss can't be persuaded to change his mind, the priest could advise him to beat up the enemy instead. Under those circumstances, the priest is not approving the beating, merely tolerating it to avoid an even worse outcome.
