I don't know what it is with your NTR-ish fantasies, but a scenario like you just drew is pure crap (no offense). Yes, you are right that decisions and choices should be consequent and I agree that there could be one or more bad endings, but at the same time also an equal number of good endings.
I mean what kind of satisfying game it would be if you can only choose between like 'take Mom, everyone else get killed', 'take Tracy, everyone else get killed', 'take Alice, everyone else get killed' or 'take Nora and screw everyone of your own family'. In the end entertainment is made for giving us a good time. There may be a (small) group of people who enjoy to see everything breaking to pieces, but that's a minority. Most people are okay to feel anger, sadness etc. ON THE WAY to the end, not at it.
So no, your scenario would be a disaster since the game never got flagged 'wait for one year and then you get pissed 'cuz of only bad endings' aka NTR heaven.
