I’m thinking it comes down to those who are so short-sighted that the temptation of instant gratification is too great. Think of it like meth users. They know when they start using meth that their teeth will fall out and they will look like a living zombie, but they only care about today and the temporary high. I’m sure there’s also a touch of narcissism involved in those who make a deal with the devil. They probably think they will somehow be able to talk their way out of it, or that the rules don’t apply to them.
