Was Uzzah just neurotic?

I’ve been writing up something for the PCC about what we consider sacred, and looked back at the story from 2 Samuel 6 about Uzzah – he’s the guy who is struck dead by God for touching the Ark of the Covenant.
(picture from here)
I wonder – was he simply a really stressed-out guy? In other words, was he just someone nervous, terrified of his responsibility for carrying the ark, incredibly jumpy (totally the wrong sort of person for the job in other words) – who, when disaster struck and the oxen stumble, reacts simply as a human being to steady the Ark – and then realises that he has broken a major taboo and the stress overwhelms him and he drops dead of a heart attack?

I ask this because it would seem odd for a God who accepts crucifixion for himself to get that upset about a wooden box.
