“Pedophiles should be executed.”
Agreed wholeheartedly.
You propose executing people for suffering under a morbid temptation?
A pedophile is someone who suffers from the paraphilia (the psychological term) or besetting temptation (the moral term) of sexually desiring prepubescent children. Some know it is wrong and struggle mightily and in some cases successfully against the temptation. Some, like Sandusky, give in.
I trust you really mean pedophiles who act on their paraphilia and abuse children should be executed.
