At conception, the soul of life force is proven 'there' by the action of organized growth, as in will exercised to live. What we do not have proof of is the presence of the human spirit with the soul of life, but as in your 'cautionary' word, we ought assume the spirit is present as soon as the soul is present. 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.
