One could say capital punishment is brutal and does not deter crime.

But by that logic all punishment does not deter crime, so we may as well ban all punishment and let crime run rampant because last I checked, lifetime prison sentences do exist and yet so does crime

Honestly, that sort of punishment would not fly stateside, and we also have lifetime prison sentences, and we still have crime. Be against executions (or in Iran's case, oddball eye for an eye punishments) all you want, but I am going to need a better reason than 'it does not deter crime' because the same can be said of all punishment
