That reminds me of a conversation i had a long time ago with my research supervisor (who was a life long atheist and anarchist) about the irony of revolution as a means by which to free the people from the yoke of control. Whilst some, probably most, would welcome the freedom, but forcing freedom on all somewhat undermines the notion of true liberty. The revolutionary chant was then amended from "You will be Free" to "You will be Free, if that's what you want".
A version of the same argument can be applied to the notion of a selfless creation of life. Some may be very grateful for the gift of life, but others would rather not have it. And unless the apprecaition of that gift is unanimous it cannot be anything other than a selfish passtime of the 'creator'.
