Agreed because the idea of a baby killer is so repugnant to all in society that admitting to this would certainly weigh in at sentencing time. He is using our natural instinct to protect children to his advantage hoping we would relate to why he killed their mother. Another sign he does not have normal human feeling as his actions say the opposite. He never attempted to revive his kids just kill their mother. Nonsensical.
You say it so succinctly! Love it.
