i.e. they were too weak. strength/weakness in this sense has little to do with morality. someone who can't rise to the occasion or hasn't grown enough isn't a bad person or anything, just unprepared or ill suited. e.g. a natural selection even doesn't care if an organism was still growing and learning. They either survive (strong) or die (weak). And that's the same definition of strong being used here.
