Leaving aside ecological reasons or specific scenarios where many people (at least those people whose reproduction is not being called into question) would agree that reproducing is wrong because the child would inherit a genetic disease, live in war or poverty etc., is there ever any moral justification for reproducing? It is guaranteed that even the happiest people in the world, at some point, suffer. Any child I create will suffer when being born, they'll suffer when their dog dies, when their stomach aches or they get sick, when the boy or girl they had a crush on rejects them, when they have to worry about exams, when the other kids at school bully them, when the other 'kids' at work bully them, when they start to lose their hair, when they're unemployed and don't know where their next meal is coming from or can't pay for their child's medical bills, when they're locked up in some nursing home and they have to spend the rest of their lives unable to take care of themselves and patronized like a little child or even for no apparent reason at all (remember that something like 1 in 6 people suffers from a mental illness, the fact is that some people have a greater genetic disposition to happiness and emotional stability than others do), etc. These issues might seem trivial to you in comparison with extreme poverty, living in a war torn region or dealing with some horrible, chronic illness (or outweighed by the happiness many will experience in life) but are we justified in deciding for other people (or things) what they should or shouldn't have to endure? Yes, most infants will grow up to experience some happiness, maybe even more happiness than pain, and most will be glad that they were born but could you justify punching someone in the nose because that person could undergo a great, spiritual epiphany as a result and come to view having been assaulted as a blessing in disguise? You might also argue that it makes no sense to have compassion for the unborn because they don't exist (as sentient beings) but they do exist as sperm and egg cells and if compassion is simply an emotional desire for others not to suffer, you actually can feel compassion for sperm and egg cells, can't you? Sperm/egg cells experience neither happiness nor suffering but if to 'harm' someone/thing is to make them worse off than they were before than making an insentient thing a sentient being necessarily harms it because it will suffer as a result. Suffering is bad, to not experience anything is neither bad nor good. It would be better to not experience anything than to experience suffering. Suffering is only tolerable in anticipation that we will eventually experience pleasure or happiness again, as a result of that suffering or despite it. What do you think?
