Correct, though I prefer murder to infanticide.
Is Post birth abortion of a president assassination?
I see your point. However, “murder” has a component of legal judgment that is not present in “infanticide,” or “homicide” in general. “Homicide” is an objective observation that a human being was killed, while “murder,” “manslaughter,” “gross negligence,” or “No charges were filed against the homeowner,” depend on additional circumstances.
