Japan was already defeated*, how would the bombings have prevented those crimes, since they weren't being committed anymore?

The bombings were justified for revenge?

* It was a formality, the Soviets were about to invade Manchuria, we should have just blockaded the Japanese mainland and let events play out, not evaporate 100k civilians.

(There is nothing particularly special about the use of nuclear weapons here, the bombing of Dresden is just as indefensible).
