Okay, it seems that we've more or less exhausted a discussion of the possible exceptions to the general inference that Men tend to be evil unless they have some kind of experience with the Eldar, direct or indirect.
I'm curious: why is contact with the Eldar so crucial?
What about the Drúedain? They don't show evidence of contact with the Eldar, and yet they also don't seem to show any inclination towards evil.
