I'm just playing devil's advocate here. I don't think what the guy did is okay, but he's also not really trying to control that woman's body. He just doesn't want to be part of something he's completely against. Imagine if you traveled in a Sharia law country and people asked you to push a homosexual off a rooftop, if you don't do it, people would talk about you the same way you talk about this guy right now. You wouldn't be trying to take control of anything, you would only be trying not to be part of something you don't believe in, same for this guy, he doesn't care about controling others, he just doesn't want to be part of (what in his mind is) killing a baby (even if the pregnancy couldn't come to term, irrelevant in his beliefs).
Just saying this is not about controling others, it's about sticking to his own belief system. The same counter argument could be made about the women trying to force this man to ba part of something he doesn't want to be a part of. In our society we consider many working people to be at our service because of the extremely wrong saying "the customer is king". There's a lot of shit these people have to put up with just because a large amount of customers are total douche. Now, again, that's not the situation here, I'm just saying this because that's where our own societal belief of professional servitude comes from.
