Hubris and overreach are a married couple, and it always ends badly. Somebody gets away with something without fail long enough, they start to see it as an entitlement from the universe, as an intrinsic part of who they are as a social agent. At some point, ‘it,’ whatever it was, is no longer about ‘it.’ It becomes about proving that self-constructed, perhaps oft-validated truism, gazing upon that edifice of self by ‘showing them,’ one more time. Placing the ‘can’ ahead of the ‘should.’
Rarely is ‘justice’ involved in the downfall, as fiction or our idealized sense of ethics would have it. It is simply the determinism of self-delusion and a sort of primitive nascent evolutionary primate urge to ‘win’ by pounding one’s enemy, and then pounding one’s chest symbolically to drive the point home to onlookers. And the more plugged in to an ‘in’ group one is, the more susceptible to this flawed logic one becomes. Ride the monster too long though, friends, and it’ll getcha.
