Biden performances like some animated Zombie a threatening gel from a science-fiction horror movie

Here is a man who has known tragedy in his life, the loss of children,  but instead of taking a reflective observational back seat of reflection, the cancer of ambition and hubris powers him on, I don't know, the word decadent springs to mind when one sees Joe Biden selling himself

I ask Raymond for his thoughts on Biden

'As an adjective, the word"decadent" functions like a coating, a sleek enameled skin applied to the "unhealthy" but not fully sinful; as a noun it exists as a disturbing substance with shifting blob outlines, Biden performs like some animated zombie a threatening gel from a science-fiction horror movie

what's the word for  him? he is 'ductile' pliable able to be deformed without losing toughness.
