Sorry, but if one's actions cause the suffering or harm of another, intentional or not, that person should be held accountable for their actions.
SO, intention is key, eh, Nick. Okay, what if a drunk driving his car, who has no intention of killing anyone on his way home, runs over and kills someone. He had no intention to kill that person he ran over so he shouldn't be charged for vehicular homicide or manslguhter?
