Your first responsibility is to yourself and to your own goodness of heart.
I heard Zen teacher one time talking about abortion, and he was saying the way that abortion makes bad karma is any time the person involved pretends that there's not a cost to the choice, one way or the other; whether you get it or don't get it, there's a cost. That's just basic responsibility, to admit that there's a cost. And the bad karma is when you pretend that the thing is free.
Our first responsibility in all things is to preserve our goodness of heart - then and only then act.
