I don’t think being dumb or gullible precludes you from being good. His heart is in the right place. In a fictional world of super heroes and villains, I’m unsure if he’s operating within vigilante laws. I think he’s dumb enough to not know what they are and attempt to follow them. If he was willfully ignorant of the law it’d push him toward chaotic. So I’d say he’s definitely neutral.
I didn’t censor it, but it’s probably enough to pass by some image recognition.
