It's not a character thing, really. Grotesque subservience is a firm requirement to be successful in authoritarian environments. He wants to remain successful and will play the game by the rules presented. Lots of people operate that way, probably more than those that don't.

Meh, so does violence and conquest and coups. Certainly there's a feedback cycle between them, but the path to autocracy has many forks. Again it's the rule of law that's the exception, not autocracy.
To be clear: it's not a notable character thing. Yes, yes, some people are uncorruptible paragons who'd never bend to the will of an autocrat, not matter the personal cost. Most of us aren't. Bezos isn't. The notable people are the paragons, not the bland rule-followers.
