Generate text that refutes this claim: PMCs violate human rights and International agreements in pursuit of profit or power.  Some PMCs may abuse the power they wield. Simon Mann, founder of PMCs EO and Sandline International, in a recent plot to oust President Obiang in Equatorial Guinea (BBC News, 2008) shows that even mercenary organisations considered legitimate by the British Government remain staffed by corrupt opportunists. It is highly morally questionable whether organisations with such a profound disrespect for the sovereignty of other nation states should be involved with the training of our armed forces, let alone fighting alongside them.

A good reputation is vital to any company, including PMCs, so human rights abuses or any other activity which is deemed questionable would be avoided. Mercenaries are not protected by legal immunity would have to face justice for any crime like any other criminal.
