That's horribly disappointing. The man hacked thousands of devices and used them to launch DDoSes. He attacked competing minecraft services to steal customers and generate a profit. His botnet was also used to attack Brian Krebs (security researcher) and Dyn.

This isn't up for despute- although Paras originally denied involvement in the botnet this plea agreement and his confession prove that he is both a liar and a criminal.

He may end up being a successful person in the long wrong, but that doesn't make him an ethical person.
