My response was concerned only with those means of birth control that may either work by preventing conception or by inducing abortion, with no certainty as to which outcome will occur.D1W1 wrote: ↑Fri Oct 12, 2018 4:53 pm
It's not to abort the developing of fertilized egg because nothing to abort. AFAIK, birth control pills work in three ways, stopping sperm and egg from meeting, stopping the ovulation and they thin the inner lining of the uterus in case the first and second method fail. Other form of birth control such as IUD makes sperm difficult to reach and fertilized the egg. if it's fertilized, the egg will stop from developing because the uterus is inhospitable. We only know pregnancy does not happen but we can't really tell if the abortion is happening in the body or not. If the intention to prevent conception is danger and the intention to kill is also danger, then there is no difference.
Methods that can only do one thing or the other are pretty black and white as far as kamma is concerned. With one you're killing a human being, with the other you're not.
But with methods that are of variable outcome I think it is better to appeal to other considerations than kamma in counselling against their use. Ahimsa and compassion, for example. Appealing to kamma may simply lead someone to recklessly rationalize that she'll use the pill with the intention of preventing conception and if it happens to result in an abortion... too bad, it wasn't what she intended, so no akusala kamma.
