Faithfulness in Middle Earth

[Silver Dragon]

Wasn't the original topic why Tolkien had his books riddled with betrayals?

Every major historical event revolves around the idea of treachery...This idea is undoubtably central not only to this portion of the professors writings, but seems to be the unifing theme of his entire mythology

It is interesting how he chose to rotate on that one theme...why is that the one he harps on?
