Evil, outside of special pleading for a particular belief system, is usually framed in terms of actively choosing the harm of others (even if it is masked in deniability). There's some very important meaning in 'don't be evil' that I always liked. Even if some evil is deemed unavoidable by sheer weight of circumstances in life, the general policy should still be to avoid it if at all doable, by any philosophy I'd respect..
"Do the right thing", however, is utterly subjective. Genocide can be seen as the right thing, by a great many, many belief systems, as could complete elimination of all other belief systems. Complete stagnation lies down most 'pure' roads. Utter evil, the complete willingness to harm others at a whim, is constantly 'justified' in the name of most ideals taken in isolation.
I suppose that's a problem with business groups though - the more people involved, the more push to 'optimize' towards some ideal that gets so important, that 'evil' is no longer a limitation. All groups do evil, because there are people involved, but most businesses seem to become blind to their own evil as they grow, until they specialize in mostly doing that evil. Well, until those outside the group start reacting to their actions, then they seem to asymptotically bounce against, and push out the ethical line.
Fortunately, the end result isn't so horrible, by most standards, basically ever measurable aspect of culture has reliably improved over time, from freedom, to intelligence scales, to health and others - but it's just interesting how groups specialize and play such strange roles.
