Drop the /s and you’re right! We can’t fix people’s desire to murder other people. We punish harshly as a deterrent but unfortunately someone who’s in a place where they’ll murder someone usually isn’t weighing the risk or making a list of pros and cons. So people get murdered. It’s inevitable and there’s very little we can do to prevent it in general.

The point it is isnt a justification to let people go around murdering others.
