Evil in a co-op means something different than evil in a corporation.

The corporation at the end of the day will lean back on profit motive as the core underlying value. This value , to a co-op, isn't inherently evil, but is often evil.

The co-op will happily sacrifice the co-op for the good of the members if push comes to shove. Whereas corporate shareholders constantly vote for things that result in e.g. layoffs, downsizing, restriction of benefits, salary freezes.
