I'm not even active right now but I have got to break my silence about Mashiro. I swear his whole "becoming god" thing and being the most infuriating man on the planet is so definitely punchworthy but how I see it, he isn't doing all this solely for a power trip or for innately selfish reasons and I honestly think it's the opposite. He just goes about it in a way that appears so self-centered that it overshadows his intentions.
For one, the man did win the previous universe war to save the world. He signed the contract. Won as he did— so far, no further information on that yet— but 10,000 years later and he returns to a world once again in a very less-than-ideal state. Don't you think it would be frustrating to have all your efforts into winning this war for the sake of the entire world to be wasted and the same thing happens again? With TegaSword, technically god, still in the middle of it? (not to mention how awfully shady TegaSword is but that could be for someone else to pick on)
His solution was to just... Right after obtaining GoodeBurn's ring, take matters into his own hands. Become god himself. Apparently. In order to save/fix it or whatever else he could do. And like.. He still does the whole world-fixing thing on smaller scales albeit for a ludicrous price (to which it has been shown thus far that he at least has both the heart and respect to do free work either way especially on fair terms). You can tell how deeply in line he is with his moral code and his original goal even when he acts all pompous and shit. He might be an ass about it but he's still heavily tied to his sense of justice and fairness. His sacrilege (against TegaSword) is somewhat his way of rebelling in an attempt to dismantle the very system that went against his wishes and ultimately failed him in order to build something new, based on what he thinks is right.
You could tell how much he cares about people and suffering and (un/)fairness. I noticed how it prominently shows through his morals— episode 18, for instance, had him angry at BearKuma. His morals in that instance came first— that even the supposed death of his enemies/rivals were something he resented (Though... Wording it in a way that it goes against him as a god (work in progress title). Yeah). His subtle expressions and reactions did show that even then, he still cared deeply about that darn plastic toy bear tank. Or, well something like that. Y'know. I could cite a handful more examples but episode 18 in particular I think about on occasion because it shows how he can really angry— at wrongdoings. Injustice, in other ways.
He's such a weird character because he seems quite attached to his idea of godness goodness while also being quite morally strange on some level like charging his world-fixing work like that. I'm reading too into this aren't I. I definitely am. Anyways
