I believe the message Oda wants to send through this backstory was "over relying on one thing is bad". And that Harald should've balanced between a peaceful route and military might.
The chapter subtly hinted that Ida actually was a little concerned about Harald going overboard with his peaceful route:
And In the very same chapter Saul also further showed this doubt:
I wouldn't really consider Harald a "bad" character. He is bad in the sense of choosing bad choices, but he served his central role in this backstory as a
scapegoat so that readers can realize there's absolutely no way to "coexist" with the World Government if not a literal slave, setting the endgame war to take it down.
Throughout 800 years all Elbaph's kings were probably ruthless warriors, then Harald came and changed it but leaned too much towards the
opposite side of power.
@Elder Lee Hung All in all? Loki will be the first Elbaph king ever to rule with a balance of
peace and
power.
