I don't think that. I do think he made a mistake in the case of the Whiskey Rebellion, and that mistake caused more damage than Washington realized. The unintended consequences of that decision led to some of the things that Washington was against.
Had he known the total effect of what he did, it is my belief he would have chose otherwise. I have the benefit of hindsight and he certainly did not, so I will not fault him too much as his overall contribution to liberty and America was outstanding.
