Possibly the best Series?

[JHyde]

I think he knows, like Churchill, that democracy is the worst form of government. Until you compare it to all the others.

But it's more than that. He has an inbuilt respect for idealism based upon something more than blind faith, usually an intellectual belief. I love it when he says about the Home Secretary "You know it's not all bullshit with him. He does actually believe in all that [British survivalism]. Bless."

Spoiler: show

It's also why killing Kachimov is such a statement. Because it's not normally his way.

I also think that some of these ideals go back to his time in Northern Ireland when we know he did self confessed "terrible things" and they didn't work. He has an unshakeable belief that once you do such things, you lower yourself to the enemy's level.
