I also question whether he has "good motivations." He wanted to dominate commerce. Not just books, but everything sold. This is not a good motivation and Amazon should be getting busted up.
The average person has had much less negative impact in their life than Bezos, but they have also had almost infinitely less positive impact as well.
In other words, it doesn't really make sense to zoom in on the failures Bezos has had without putting them into the context of his successes.
And I've never really seen a clear-headed examination of Bezos' positive and negative impact. My guess is that he's doing extremely good overall, even if his negative impact is a bit higher than would be ideal.
This is similar to how many people claim that technology, or even social media, is an evil force in the world while completely ignoring the massive good it has done for people (grandparents living richer and more connected lives with their grandchildren, communities of people supporting each other, political organization, etc).
