I don't believe in karma. Or some sort of invisible balancing force of justice in the universe. But I do believe they are low-lives. Almost guaranteed incapable of experiencing certain joys that decent, well-meaning people are. And their willingness to scam...means they're almost certainly chronic liars. To the point where they don't even know what the truth is anymore themselves. So they live in a world of fabrications made on the fly with their own mouths. They won't ever know the joy of a trusting relationship. Projecting their distrust on everyone they ever encounter in a constant state of paranoia. And adding one more "but what if he knows I know he knows" as they stack to the point of insanity. Then, periodically, they are filled with a sense of sheer panic as they realize they don't even know what is what in the world. Because they have deceived others, and therefore themselves, to such a habitual degree, they don't even have basic truths on which to function.

Grizzly bear was an impulsive anger expression. The Hellish existence above is actually highly probable. That's the scary truth of that path.
