IT IGNORES EFFECTS
The main criticism of retributivism is that it pays no attention to the effects of the punishment on the criminal or on society. Questions of deterrence, reform, and protection are irrelevant. According to retributivists, criminals deserve to be punished whether this has a beneficial effect on them or not. Consequentialists object to this on the grounds that no action can be morally right unless it has beneficial consequences, to which deontologists might reply that, if an action is morally justified, it is so whatever the consequences.
