Oooookayyy, what?
You don't think human intervention interrupting natural process of death is unnatural?
I think that is a very broad statement and I wouldn't entirely agree with it. If I saw you choking in a restaurant, would you mind if I interrupted your very natural death process to administer the Heimlich maneuver? If you were stung by a bee and stopped breathing, would you have a problem with someone administering CPR?
Technically, those are interruptions of a "natural" process.
