Historical accounts are always biased, usually according to the political correctness of the time they were written. For example, the Founding Fathers went from hero to goat to hero to goat and are now morphing back to heroic status with the play "Hamilton".

Civil War heroes are goats today, even having their memorials removed.

Edison has gone from hero to goat. He'll be a hero again in a few decades.

It's the job of a professional historian to try and discern the truth from all this. But whatever truth there is in fiction is impossible to determine if you know nothing about history.
