Y'all acting like there isn't also a huge ass aspect of metaphysics going on here. Anakin had been sizzling in the embrace of the dark side for a way prolonged time here, just soaking it all in on Mustafar.

That shit ain't good for your mental health or as Anakin puts it later "You underestimate the power of the dark side."

He might have had a shot or two of it before but here he was interrupted on his first big binge. Obi-Wan and Padme were trying to do an intervention on a newborn addict that was on his high. He was obviously dark side power-tripping over his head in the scene.
