A baby is born: creation of complexity and life for which one can be said to be responsible, but. We are and remain ignorant about the intricacies of the real process. One can decide (not always). This is managerial responsibility, not engineering knowledge. Perhaps that's why we can be so surprised about our own happiness sometimes: do we really deserve to be happy, when we did not do much effort - sometimes it was even pleasurable... that one can be happy while ignorant, receive good and take credit when having done little: all this does not match very well our judeo-christan precepts. That's why we are jealous of animals: they just live, enjoy life without forcing themselves to deserve it by mental feats (or so we think).
