Should punishment be based more off of intention or result?
Purely result=death penalty for accidents
A little bit of both.
Both. If I have an intention to burn down my factory for insurance money and start a fire but didn't know there were 10 people still inside who died. My intention was not to kill anyone but they died. I didn't accidentally drop my match, I set it on fire and people died. So though my intent was not there for people to die, they did. I need to be prosecuted for their deaths even though that was not my intent.
We all would like to be judged on many things based upon our intentions; however, usually the only available information for others to judge us upon, indeed, are the results.
