Do you really think that the law should make no difference between those with intent and those with lesser degrees of culpability? If an innocent dies while you are committing a crime, then yes, your intent isn't relevant. I mean, what you are asking here, is for a complete abandonment of hundreds and hundreds of years of legal thought, that has been working perfectly fine. I don't agree that it works fine. Especially not from the victims perspective. For ages it was fine to beat the wife on the courthouse steps. Times and attitudes change.
Now you advocate the execution of thousands of individuals based on dubious evidence that you think it will deter people slightly from doing slight misdemeanor crimes. Actually IIRC I mentioned speeding up the appeals process.
I mean, why only execute them in the remote possibility that it happens to cause a death? Why not execute anyone for doing anything at all that could lead to a death? If it could lead to a death there is a chance to stop it. How remote is it that drunk drivers kill people?
A person walks out on the highway whenever your driving 65 - that's perfectly fine. A person walks out on the highway whenever your driving 66 - ZOMG WE HAVE TO EXECUTE?! Do you see the irrationality of the extremely broad test you're applying? It's the reason mandatory minimums don't work and result in so many miscarriages of justice, and applying a mandatory minimum of death has been declared unconstitutional in any case. You are discussing deterrent values. I am not worried about deterrent so much as I am about killing the killer so they cannot kill again. So, if you are a law abiding citizen and accidentally kill someone..... it is understood that you did nothing wrong and the death was a tragic accident. If you are a criminal and during the commission of a crime you killed someone, you deserve to die. Had you chosen not to commit the crime that person likely would still be alive.
There are 3 different levels of culpability - intent, recklessness, and negligence. Doesn't that make sense, that we don't punish anything but "intent" with the death penalty, and even then it's only applied in levels of special heinousness? It has made sense for a long time. Just think about this stuff before you say it.Actually I have thought long and hard about it. Your three standards do not make sense, are overly lax, and allow killers to not suffer the fate of thier victims.
