Depends on the intended meaning of the word: exploiter. Humans tend to be opportunists and can be equally exploitive of one another and of the environment so the word is likely applicable to us all. Eps seem to have natural abilities to take advantage of something in a parasitic sense because they're often the first to notice an opportunity or opening. Ejs have natural abilities to bring things/people together and make things happen but that doesn't indicate a greater exploitive urge......
