Just curious, what can we say on the issue if we ignore the origins of the death penalty? Screw old English law, let's scrutinize the death penalty under the current zeitgeist for a second to debate it.
Personally, I've had a childhood friend raped and murdered with her body left in the woods. The man responsible was caught and convicted and sent to Death Row. I agree, and everyone who knows him including his family are in agreement that he should die, and many of them are frustrated that it takes so long for the execution to occur.
I also know that not every judgment is perfect, that the system did not start out with a 100% success rate. I think that as we improve our current system of forensic analysis and understanding we can feel more comfortable in sending the proper person onto death row.
I also think they should die in the fastest possible time after judgment.
I also think all those who are locked up and NOT on death row, just people who committed crime(s) should still be offered an education, food, and the like just like I'd offer any human being. I also think they should work for the amenities however not like slave labor. Even a prisoner can learn to index a file, write a dissertation. Don't waste resources.
