defining "evil" would be a good start, though we seem to have failed to do it for the last ten thousand years :)

More seriously: there are plenty of "ethical certification" thingies, and lots of finance entities who only work with "ethical" products.

This things just don't seem to have trickled down from (arguably) major evils businesses (child exploitation, war profits, environmental disruption etc) to lesser ones (predatory pricing, patent trolling, exclusive dealing etc).

Possibly a matter of time, but a long one IMVHO.
