Dr. Robert Sapolsky on Faith . This guy is always enlightening to listen to.
Funny, but years ago I took a Great Courses course on the workings of the brain. He was the lecturer but it was before he grew the beard.
I agree with his take on 'forgiveness.' Some people simply do not deserve to continue living in a society and right now I can think of numerous people in our political system.
Years ago there was an, in-depth study by the Germans on gun violence. One thing I noted was that in a society with a high crime rate (as ours) people feel the need to be able to do something to relieve the pressure and capital punishment is one way to this end. Want to get rid of capital punishment reduce crimes especially serious ones. The most serious crimes are often those caused bu mass murders with guns.
