Just because your ethics require an action doesn't mean the universe will exempt you from the consequences. Manufactured cars kill an estimated 1.2 million people per year worldwide. (Roughly 2% of the annual planetary death rate.) Not everyone who dies in an automobile accident is someone who decided to drive a car. The tally of casualties includes pedestrians. It includes minor children who had to be pushed screaming into the car on the way to school. And yet we still manufacture automobiles, because, well, we're in a hurry. The point is that the consequences don't change no matter how good the ethical justification sounds.
