My guess is the decision is more on what to do with the pregnancy.
Probably whether to keep it and raise w/ support of family even though wife is in coma (possibly risking wife's life), or decide can't raise on own/abort to keep mom safer. But, to many that would still be considered a live or die decision. ( I *suspect* though by saying it isn't live or die, Killer7 is saying it's precisely NOT what you are suggesting. Not that it isn't about aborting/not aborting the pregnancy.)
