Does this make it impossible to separate his approach and impact on Apple's design aesthetic?

I know a lot of people know about how he treated his employees and his textbook narcissistic behavior (which you point out) and they just disregard his behavior because of his incredible eye for design how it impacted Apple's design for decades before he passed.

Its as if the impact he had was the greater good for the company so the rest of his questionable behavior gets ignored.
