I really like this Wired article about Marcus Hutchins, who saved the world from the WannaCry virus by registering its sinkhole domain.
He comes across as very moral! He made mistakes as a teenager when he tried too hard to impress his peers. They asked him to write sketchy code, and he did it. Then he paid for it with years of anxiety, and now he is wiser and thoughtful.
He is Ged from the Wizard of Earthsea.
