It is. If there is no punishment for getting someone killed, then why would anyone give a shit at their job that involves safety? Airplane mechanics are held responsible for their failures, should we throw that out the window and when they forget to tighten down a bolt that drops a plane just say whelp, better luck next time, lets get George some more training and hope he follows the procedures that are in place to prevent that from ever happening again.
If there is no consequence, then there is no need for rules and laws.
