If I do my calculations correctly you just need to stab someone once , not twice- because they will already loose a lot blood in the first place-
So basically:
If you Stab someone once then they are technically dead
If you stab someone twice then they are still dead
If you stab someone three times then you technically don’t want them in your life-
(Sorry if I offended you and don’t understand the joke-)

You just stab once because they will be dead , unless you stab them in the heart once- but the point still stands! It isn’t necessarily to stab someone more than once (because they will be already dead in the first place)
