>We lack information to asses the full consequences of our actions and so any morality based on the ultimate results will be unworkable.
So then what should we do? If any morality based on our small understanding of suffering is largely unknowable, then why should it be immoral to eat animals? Furthermore, is this a question of knowing, or is it universal? Is it alright for tribesmen to kill animals if they haven't even considered the animal's suffering?
