Our characters are evil, main quest proves it.

[Toranja]

Gaius : Lawful evil
Ascians : Chaotic evil

As simple as that

Lahabrea states he is out to restore order by awakening his God and that Hydaelin is the cause of the imbalances. Doesn't sound very chaotic to me.

By the way, he is just making his case, stating his view. For all we know and judge, the World was in balance when Hydaelin was the only one running the show.
