If you hold all the personalities of previous eras to today's moral standards, whom will you be left with?
Let me explain my idea on another, more clear cut example. Ancient Greece and Rome have been built on slavery. Almost all powerful and even educated men of that time used slave labour. Should we remove them from philosophy books and rename the months?
Should we just proclaim that everyone who lived then was evil, except the poor and the slaves themselves? But even they didn't hold some higher moral values, they just didn't have the means to enslave other people. So, we probably should say that everyone in ancient world was evil, period.
