That's my opinion about the first question too. With the 2nd one I was imagining something more basic, like encountering a woman killing an (already born) kid and deciding whether I should try to intervene or not, but the essential question of whether intervention is ever OK is the same.
You raise a good point about a 3rd option. I wasn't trying to assume responsibility and this just didn't occur to me. I meant "parent" only in the physical sense. Maybe becoming pregnant imposes no responsibility whatsoever to be a parent or part of a family. In that case, if you said the answer to 1 is yes, you probably think the child is not hers, but is an independent person (?) so there are still problems.
I don't love the idea but am not saying I'd never do it or that anyone should be forced not to.
"The child is not her's, but is an independent person" correct. I agree, this is about making sure we know what we will do the moment we are confronted with the situation. The truth is that the Government will most often not conduct the best action.
