Argument: Executing killers is not comparable to raping rapists
"The Death Penalty: Morally Defensible?". Casey's Critical Thinking - "Abolitionists often insist that if we argue for lex talion justice we must be prepared to rape rapists, beat sadists, and burn down the houses of arsonists...Why then, if it is not morally okay to rape rapists, is it acceptable to execute murderers? The answer is simple. There is no redeeming value to carrying out the former punishment. Raping the rapist will only cause someone else to degrade themselves by doing it. It will not prevent the rapist from raping again. Executing murderers, however, prevents them from committing their crime again, and thus protects innocent victims. The good, therefore, outweighs the bad, and the executioner is morally justified in taking the murderer's life."
