Which part do you consider dehumanizing?

I've been on both sides (IC + manager), though not at Amazon. As a manager, it's always crystal clear that not every team member contributes equally, often by a wide margin. When it comes time to give out monetary rewards and title increases, how would you propose people be evaluated?

The only part that really makes me shudder is the thought of working to align with Amazon's 'principles'. Sounds like an oxymoron to me.
