Harald wanted Elbaph to be part of the WG, while Xebec was against it. Some people might said Harald was wrong simply for what happened to his life. But, I will say what Harald did was logical. Elbaph was in crisis, and no other country wanted to exchange trade with Elbaph. Harald didn't want to be barbaric and invaded other countries for resources. Joining WG would give more benefits for the country. What Harald did was not perfect, but it makes sense
