Are they pedos?

So during olden days or even during 1990s people used to marry young kids right, mostly girls I would say. Back in the day it was a normal thing. Among these people there were scientists and great human beings...Are they pedos without knowing they were pedos? Definitely in today's society according to the definition they are pedophiles for marrying young kids but back then they weren't. Are they criminals? What do you think?
