why should we as humans decide who lives and who dies?
Everyone has an inalienable human right to life, even those who commit murder; sentencing a person to death and executing them violates that right.
This is very similar to the 'value of life' argument, but approached from the perspective of human rights.
The counter-argument is that a person can, by their actions, forfeit human rights, and that murderers forfeit their right to life.
Another example will make this clear - a person forfeits their right to life if they start a murderous attack and the only way the victim can save their own life is by killing the attacker.
The main argument that retribution is immoral is that it is just a sanitised form of vengeance. Scenes of howling mobs attacking prison vans containing those accused of murder on their way to and from court, or chanting aggressively outside prisons when an offender is being executed, suggest that vengeance remains a major ingredient in the public popularity of capital punishment.
