Very good points. He reminds me of the WW1 generals who sent soldiers running from the trenches, knowing they’d be mowed down. He’s in the process of leaving, knowing the place is going to be destroyed, but demands the staff remain at their post. I like his Blofeld a lot - he’s a cold hearted snob.
That attitude for Blofeld does also crop up in FRWL and YOLT, this view that everyone but himself is expendable, but none are clearly having as much fun with it as Charles Gray.
