The death penalty works GREAT! It prevents those who receive it from ever killing another human being or committing a heinous crime. Would I push that button? You betcha. Especially if it was MY loved one who had been killed. I find most people opposed to the death penalty have never had a loved one murdered. I have.
It does not deter OTHERS from doing so, however, since most criminals do not think they will get caught.
This is case that has been in the news recently because the trial has been ongoing, but 2 men in Connecticut are accused of following a mother and her two young daughters (the youngest was 11) home from a store. They forced the woman to withdraw money from the bank; she also calmly told the teller to call 911 and send them to the home. They broke into the home with the entire family home, bludgeoned the father, tied him in the basement, then they tied each of the females to their beds, raped them and SET THEM ON FIRE. They died in unimaginable horror and pain. The jury was shown photos of the charred bodies still tied to the beds, remnants of the pretty bedding and charred stuffed animals visible to remind them just how helpless these victims were.
Police arrived as the men were running out of the house. They were caught, but only the father escaped the fire- he had been tied up, but he got out.
One of the perps who had raped the 11-year old took photos of it with his cell phone and also photos of her terror as he set the fire. He wrote in his journal how much he enjoyed it.
Think about this and tell me you honestly feel the world needs someone like this in it. What if it was YOUR daughters and wife? Or sons and husbands? Some people are too evil to be allowed to remain here.
Sometimes God wields his own death penalty (stage 4 ovarian cancer?). Sometimes LE has to help him out.
