I think we should be harvesting the organs of death row inmates <---Yes, I saw this on a youtube vid and thought it was a great idea. If we could save a bunch of lives because of people who were too dangerous to live had healthy organs, then I say we keep the death penalty around. It does bother me that some people are innocent in death row, and get executed, but that would cause the justice system to look bad, and then there will be more caution in people who work to investigate things. Other than those rare cases, these people did kill, and there is no changing anytime soon to the death penalty.
Your opinion on public execution doesn't make sense. People kill because it is an uncontrollable urge that takes over their minds. There are hardly any would-be killers, there are mostly people who kill and don't realize what they are doing. People only want public execution because it gives the victims happiness to see somebody die, just the way it gave that person being publicly executed happiness. It's simply primal.
When it comes to the organs being healthy, they've banned cigarettes and alcohol, along with any other drug, and their food is the essentials, so they should have healthy organs. Like any organ donation outside of a family, it needs to be carefully done, and checked throughly.
by the way, why would somebody be publicly executed for treason? It's not that serious.
