Agreed and this data tends to backup that assertion:

View attachment 18509
"The threat of execution at some future date is unlikely to enter the minds of those acting under the influence of drugs and/or alcohol, those who are in the grip of fear or rage, those who are panicking while committing another crime (such as a robbery), or those who suffer from mental illness or mental retardation and do not fully understand the gravity of their crime."
Absent from this chart is anything useful. Like, the date the death penalty for a specific state, and the specific data for that state, was implemented. So, if that red data series was for one state, and that one state had the death penalty enacted in 1993, then it perfectly well shows the deterrent effect.
You are free to ignore the data. God Bless America!
The bottom line for me is that taking a citizen's life is the harshest most authoritarian thing a nation can do. The most egregious thing a nation can do is take the life of an innocent citizen. Executing someone like Bower's, Timothy McVeigh, Saddam Hussein or anyone else who is 100% guilty is not a problem for me. Same goes for those so murderously insane they are a danger to anyone around them. It's like putting down a rabid dog. For others, I'm less sure and am against the death penalty in those cases.
