Hmmm...incest..a brother and sister? Both adult? Rape..Don't the raped women know they have been raped? Don't they get cleaned out?
Life of mother. I agree with that. But the only thing I can think of is a tuble pregnancy. The baby will die, too.
I agree with you.
In the case of rape and incest, the child is paying for someone else's crimes with his/her own life.
In the case of grave danger to the mother's life, for me, it's acceptable in the 1st trimester.
