On the ‘killing the indigenous looks bad’, it reminds me of something in corporate Watch’s Corporate Law and Structures report:

For most people, economic values are secondary, and social and to a lesser extent environmental values come first: making money is good but only if it doesn’t conflict with believing it’s wrong to murder, steal or cut down virgin rainforest.

For the corporate ‘environmentalist’, profit is absolute, social and environmental values are relative: their first aim is to make as much money as possible, but given two ways to make that money they choose the one that requires the least murder, blatant theft or environmental destruction. Then they pat themselves on the back for being so responsible.
