Hae Mo Su’s mistake was that his too-strong emotions and compassion ultimately led to his downfall. When he came to power, this naivety eventually led to the division of the Da Mul unit.
A king in power should not trust everyone and should not be naive.
But Hae Mo Su’s son, Jumong, was a man who thought through every step he took.
And he assigned duties to his companions and gave them the authority that belonged to them.

However, as they say, an enemy from within is the worst.
It was the traitors from within who brought down their own Korean brothers.
