He had a general feel on how strong the other people in that room except for the self-proclaimed goddess...couldnt he just wiped everyone there and forced them to listen? I swear to god, japanese stories tend to overly make their characters polite and kind, when they make them "evil" theyre barely evil and more of just selfish... Hope they fix that sometime in the future because if not, the other countries "anime/manga" might actually surpass japans if not already..
