Ok, first of all, try to cool it with the Rhetoric. Hell the entire point i was trying to make was the fact that as a person. We really know nothing about him. We don't know why he did what he did. We don't know his true goals. As right now your just judging him by the cover.
Further more, as lets take an example of the birds. Why dose he hate the birds so badly? Well maybe it was because their the reasons Sadia Got kidnapped to begin with? For all we know he holds a grudge against the bird servants for that. And what would cause such a thing? Well take a look at panel 11, where Sadia is captured by volcano dragons. I wonder how that could have happened? What if the birds did something stupid and got her captured. And her Angry thunder god brother decided to hold a grudge over her sister getting Tormented to death..
See, this is why i say we don't know much about him. Because in the end, outside of Being powerful, Caring a lot about his sister and being in this whole Eye plot. We really don't know that much about him. As sure he could be a horrible monster. Or could just be an overprotective brother who is still angry about His sister getting captured and nearly murdered by volcano dragons.
Side note, I would not trust anything the Trailed rat said. As sure they could be trying to unite the eyes and become Uber gods. Or maybe he could have been lying to them. Considering what he did with Roko, and that he is a 8 tailed fox. I would not really trust him as a good source of information. If anything he has more to gain by lying to them to get whatever he could have wanted out of them.
Ps, i still think sadia cares about her brother. But is unwilling to admit it as she knows it would upset brand. As in the first panels he was introduced. Kinda seems like he actually really cares about her. willing to fly her around and what not. We really don't know their relationship that well. as Sadia, like is said before. She likes to hide things she doesn't want to talk about.
