Yes people are evil and these people manifest themselves in the form of corporations, governments and agencies. There is the second system effect as well where one of the mechanisms above manifests itself as something evil when the components are thoroughly innocent. An example of the latter is your typical defence contractor. Also reference the film "The Cube" which discusses this as part of the theme.

People are definitely evil when they shrug off the moral implications of what they're doing for a pile of cash or turn a blind eye to the consequences of doing something. There are a lot of evil people on here and each little action adds a paper cut to society.
