Although I support the death penalty under certain circumstances, I don't think it should be a public even in any society.
My reasoning is this: In certain parts of the world violence and bloodshed are every day occurrences and these people are not deterred by seeing or hearing that someone has been sentenced to death. I do however believe that the law abiding part of society does not need these criminals amongst them. They should not be expected to pay for their incarceration. Bluntly, any society does not want or need these people amongst the population.
I therefore believe that anyone found guilty of crimes such as pre-meditated murder, rape and paedophillia should just be removed from society and disposed of quietly to rid society of them.
No one argues with that, but you don't say how exactly they should be isolated from society. If they ever include the expense of taxpayers ' money that is not an option. Even human rights defenders are constantly screaming about the poor conditions of detention. It seems to me that the death penalty is the way out of the situation.
