I'd disagree on that. Humans are made of cells and yet we are ready to talk about humans not just cells. It's a higher level of abstraction with its own decisions. Same way, companies are made of humans yet they have power structures that make them behave in unique ways. They make decisions based on processes that maybe no human would approve. Sure, there is often a catalyst leader but the organization can move on without it.

I get your point, but what prevents us from considering "evilness" an emergent property of organizations...?

What makes certain agglomerations of atoms "living beings"? I don't see a fundamental distinction between "alive" and "not alive" that would apply to humans yet would not also apply to larger organizations.

Now, the question of whether certain companies should be considered "evil" may not be something I want to spend a lot of time on, but the arbitrary philosophical distinction that only humans within those companies can be "evil" makes the discussion even less interesting.

Companies have a culture, which evolves over time and is driven by humans and their morals/priorities, reflected in their actions and handed down through "generations".

Yes, they can be evil.

Odd to consider an institution incapable of being beneficial or harmful to society - my best working definition of evil not steeped in religion.

Aren't companies "moral entities" by definition?

You are wrong! Corporate person hood is a thing. It just turns out that the definition of a corporation could also be the definition of a sociopath.
