I do not believe the man wanted to be king. The comment on Bertie being better suited for kingship than him, the continual (deliberate?) venture into political commentary, his comment (after coming to the throne) that if they wanted his father for king again - they could have Bertie, his irresponsibility when he became king (leaving dispatch boxes open and laying about), he was not into responsibility, just adulation. He thought his 'personal popularity' would carry him through, and was actually shocked to realize that HE had to do HIS bit before they would back him - and his bit was not to marry a woman who'd been around the world (in more ways than one) more than once and carelessly left living husbands in her wake. Her mistake was believing him when he said he'd make her Queen; his mistakes are numerous.
