This is gonna be pretty unpopular (perhaps rightly so), but I have been considering having the option of doctor assisted neonaticide (killing the newborn right after it's born). I'm not going to say that other peoples moral reaction to this is wrong, but I am not strongly opposed to it for the following reasons.
Potential Benefits
Moral Justification (Again, just my opinion)
Potential Downsides
Opening up the possibility of selection based on sex (this can already happen with current technology).
Morality of such a procedure.
Potential mental heath effects on parents.
Anyway, this will likely never happen because of the sensibilities of people. So it's more of a moral thought experiment than anything real.
