Why have jail for any crimes then too, right? Criminals won't think well of the justice system if we have jail, so they'll commit more crimes to spite us. Right? Be serious. Deterrence may or may not always work, but it works enough of the time. Even when it doesn't work, the alternative (leaving them alone) almost certainly wouldn't work either. People who do these awful things don't need new grievances -- all the old ones will suffice for them.
