Death penalty doesnt fit modern society. Not to start with the horror stories of innocent people sentenced to death...
Also look at Rodrigo Duterte. Killing because of drugs..? Jesus.
Why do you say that death penalty doesn't fit the modern society? What do you suggest as a replacement? I am fine with life without parole in a penal colony. But then you will say that such punishment is too draconian and doesn't fit with the modern society as well. I am NOT fine with your suggestion of keeping the criminals in a 5-star facility for a few years and then releasing them back to the society.
