The question is not whether he deserves execution (he does), but whether we should execute him (we shouldn't).
In the USA, executing people does not reduce crime, protect people (at least if incarcerated in more protective prisons), or save money compared to long term imprisonment.
Executing people hardens us as a society to others. All systems of capital punishment there are systems to protect the executioner from the deed, showing the recognition of how such acts are bad for them as human beings, even when they agree in principle it's moral.
In the US, the evidence & ethics are against having any executions.
I am challenging any death penalty opponent â there are millions of them, allegedly â to step up to the plate right now and explain why this guy should not be executed. His guilt is established beyond any doubt whatsoever. His crime is utterly savage and heinous. Tell us why he doesnât deserve to die. Go ahead.
