If abortion truly is murder, as you believe, it cannot be allowed. If, however, you allow murder because a child may be distant from his/her mother, should you not also allow murder if a child will have some sort of congenital disorder? Is that not worse than someone being distant from his/her mother? I would imagine allowing murder to prevent a debilitating congenital disorder is more justifiable than allowing murder to prevent someone from being distant from his/her mother.
