Not particularly, no. One should merely be conscentintious regarding the potential for bias in all accounts of everything, but not to the point of self-confirming paranoid delusion. Being critical, even skeptical, should not depend on one's perception of who stands to gain or lose from something (in no limited part because even informed observers can end up being very wrong about who eventually profits from an undeniably complex sequence of events).
