--Until someone can prove the spriit doesn't take up residence with the soul at conception but at some later date, it is an arbitrary selfish (I would say self-appointed godhood) assumption to kill the newly conceived claiming 'no human is there yet.'--
Since there is no way to prove 'the residence of the soul', yours is a false logic.
Ahem, I have stated that I believe the evidence of life directing growth and development in the individual is evidence of the soul present in that living organism (at the most rudimentary level, it is evidence of the will to live, in my calculus). Perhaps you wish to poo poo the notion of spirit present with the soul?... I can see why you're 'up all night.'
