What was the purpose of the seven heroes to name the 4 people as betrayers of their quest, even though
They were the real heroes and completed it. I understand why they were killed. Why not just let the king know that they too died after completing the quest? Why was their name dragged through mud. We see a lot of negative consequences of this, for example Kfeer's family ostracized and his territory thrown in Civil War.
Why demean the memory of their friends instead of honoring their memories?
