You said below that Dimber is a cancer.
But really, a biopsy would reveal he's just a cyst, an old one, forgotten as it slowly swelled and began to calcify over the time slipping him by. Something still to be excised, but really of no danger to anyone but himself and his incurable insecurities as his unslightliness is his only discernible quality.
He strokes himself on his 'individualist' idealogy, which is exactly that - in his puerile myopic dungeon of an inconsequential existence, he is an individual, the only individual, and everyone who isn't aligned with his shadow gets a dishonorable discharge from the rareified realm of his grandoise figment of an almost formed ego with his go-to, "Y-y-you're a leftist, so, um, blegh!"
He's not malignant, he leans more towards necrotic, a dying puss filled polyp with a wriggling botfly larva hiding within, jabbing when no one is looking, lest he be spotted and crushed as the useless maggot he is, unnoticed as he was in his absence from here after a day or two.
He's over, he's done.
