Had someone actually died, it would match the definition of "depraved-heart murder", which is second-degree homicide in many states. Depraved-heart murder is killing someone through actions not actually *intended* to kill them, but by reckless disregard for their safety.
One really messed up part of our judicial system is that punishment is often more interested in the results of the perpetrator's actions instead of the intent. There is no sane reason why attempted murder and murder have different punishments, since the intent was the same. Similarly, there should be no difference in the punishment for depraved-heart murder and reckless endangerment.
