"nor shall ANY PERSON be...deprived of LIFE, without due process of law"
Please note there is nothing in the context of this amendment that limits said interpretation to citizens or already born persons as you attempted to argue re the 14th amendment.
The constitution clearly protects ALL persons from certain unwarranted deprivations, whether or not many (or even most) judges have not thought it through.
Problem: under the common law, unborn children are not persons.
