I watched the downfall and eventual jailing of someone who had a great job, career, and family after he started getting involved in cybercrime.

As far as I can make sense of it, he enjoyed the thrill of feeling superior to others: Evading the law, exploiting people who viewed as stupid, and enriching himself in the process.

He got caught through a mistake that was really dumb in retrospect. I think he believed his intellectual superiority combined with the stupidity of others so much that eventually he couldn’t imagine anyone catching him.
