For my part, I think that it’s healthy to have some parts of your life which you dedicate to doing what seems morally best, and some which you treat as personal, and that having kids should clearly be treated as personal (i.e. you shouldn’t agonise about whether it’s morally optimal). And I say that as someone who probably doesn’t want kids myself, a position that’s informed but not determined by ethical concerns.
