So does that mean you are against abortion even if giving birth would result in the death of the mother? Her life would be worthless in your opinion. And if the distinction is being made between knowing right from wrong, well...fetuses don't know shit, a lot less in fact than many of the other animals people consume on the daily. And by 'just existing' you do likely cause harm to a large number of other animal species. Human overpopulation is somewhat of an issue, as is our effect on the environment. They also might not know right from wrong, which is how you distinguished between humans and other animals who are okay to kill in your opinion.
