Consider these two premises in a well-known argument: (1) everyone has a right to life (a basic moral principle), even hardened criminals; (2) the death penalty is a violation of this right. the conclusion to this argument is:

The conclusion of this is that death penalty should be abolished. nobody has the right to take life apart from the cycle of nature itself or God. Even the individual has no right to take out their life.

The main aim of sentencing a person is to offer correction measures and death is not one of them.

this is however contentious because some hardened criminals have their victims baying for revenge, and death is one of their desires.
