Everyone exploits other living things. Even a vegetarian takes and uses life. Once basic needs are met, the accumulation of resources, both living and mineral, and the power to control resources, including human resources, is the pinnacle of the concept behind "Survival of the Most Fit", and if the checkered history of this violent world confirms anything, it's that life is a cheap resource. Especially human life. As exploited life forms go, humans have been a very profitable resource. The first generation on this pale blue speck of wet dust in space to show enough Sentience to understand 'survival of the species' over 'survival of the fittest' will get to see their children reach the stars. Does anyone really need a gold pot to piss in?
