Meaning if a man decides to kill every child that isn't his, it increases the survival of his bloodline only so much as he'd able to survive being mauled by all the other men in the group.
But that's personal survival, not species survival. The behaviour of the man killing offspring that aren't his IS an undesirable trait, as it threatens the survival of the species.
