What if Voldemort became real?

As all us Harry Potter fans know, Voldemort is not a real person. As a fictional character, he's evil and blameworthy within the story, but not in real life. But suppose J.K. Rowling had the power to bring Voldemort to real life. And suppose that if she did so, the real Voldemort would be exactly like he is in the books. He'd be just as mean and nasty and evil. Would he be morally blameable for his actions?
