Moral Responsibility and Ignorance

I Doris has just driven her car into a tree. She's unconscious, slumped over the steering wheel. Perry comes upon the scene. He's shocked at what he finds. He looks around to see if anyone can help, but there's no one else there. He's wondering whether he should try to find a phone to call for aid, but visions of wrecked cars catching fire and exploding into roiling balls of flame fill his mind, and he feels that he must rescue the driver now or else she'll surely die. So, with considerable trepidation, Perry rushes in and quickly drags Doris free from the wreck, thinking that at any moment both he and she might get caught in the explosion. At last, when he judges that they are far enough away from the car, he collapses, exhausted, onto the ground, with Doris lying in his arms. As it happens, the car does not explode. Within a couple of minutes, Perry hears sirens wailing. Soon after, some emergency vehicles screech to a halt. Paramedics jump out. They run over to Perry and Doris. Perry tells them what happened. The paramedics take a look at Doris, and they arrive at a chilling conclusion: Perry has paralyzed Doris.
