I don’t blame the ninjas for not trusting Morro here

I can not blame the Ninjas for thinking Morro is there to fight, like come on look at that smile of his, no other person smiles in such a evil way. Its really pissing me off, they could’ve changed his expression to look at least a little less menacing, instead he looks just super suspicious, so of course everyone reacts the way they do. I don’t even get how wu instantly trusted Morro the moment he told him the truth, sure its his old student but he also knows damn well what messed up stuff he...
