Yes. People say have a heart, well I do. I also have something called logic. What some people fail to realize is that the more prisoners, the more money the state has to spend. They should just kill people that have committed violent crimes, most of them are psychopaths that wouldn't give two *CENSORED* about what happens to themselves or others. Psychopaths and sociopaths that don't feel emotion shouldn't be felt sorry for. Simple as that.
Hare's theory remains controversial, but a high score on his test is at least moderately correlated with both recidivism and violent criminality. Hare estimates 15 to 25 percent of prisoners and 1 percent of the general population are psychopaths.
Now getting off the psychopath train, back to the economic factor. Less prisoners = more money for the state & less taxes paid by the citizens of said state + less violent prisoners alive = better quality of life for average citizens.
In an ideal world, people who knowingly and effectively kill others should just be put down like a dog. Sure, give them a trial. But also put the thought into their head that they're going to die no matter what.
Keep the ones that are in prison for minor things, like drug possession and theft, and enter them into rehabilitation programs and the likes. Doing this along with being more loose with the death penalty would result in less crowded prisons and as previously mentioned, a better quality of life for normal people.
