I wouldn't say Karna was "trecherous" per say, since him as the highest of the Divine Ten lead the current world/story advances to where it is, like the other imperial gods would've set humanity back or destroyed it (more or less). Karna wanted to destroy humanity since he thought they were greedy (damn it Humanity, especially you Sheda), but it seems he could be reasoned with since Elimo omni mentions that toward the end. Of course, she didn't become a goddess so that's bad, but it sure didn't help humanity's case when a group of humans (damn it Lucius) seem to have sealed their leader. As for Alza, well, he seems to have been neglected, forgotten, or something like that line, so he rebeled. When you (spoilers?) destroy him, his last few lines basically says that he was always in Karna's shadow and being called Pious Emperor seems to be degrading to him, since it's not his name. He just wanted to be noticed, to be known as him and that he's not inferior to Karna, even trying trying to get someone to say his name before he faded/died/disappeared/etc., though he never revealed his name since he got cut off with his death.
