Criminal hackers believe that unless you can force compliance, there is no obligation to comply with agreements and rules. These are people with no connection to the rest of society. They are arrogant, twisted creeps who sneer at trust, despise agreements, and look down at honesty. They call us losers. They describe our belief in honour as lame.
Some criminal hackers have all the hall-marks of the addict.
They live in a subculture where dishonesty is the norm, where the rest of society is seen as lame-brain jerks who don't know enough to protect themselves. You may as well trust an unrecovered alcoholic or an active drug user. Putting confidential information within reach of a criminal hacker is like putting children within sight of a paedophile. You'd be crazy to do it. The next problem is that anyone who has been as anti-social as an expert criminal hacker is subject to blackmail.
