TBH, he deserves this slap (betrayal?) in the face. I don't think he's naive but actually stupid. Take away his super strength and he's no better than an average farmer in the sticks. Hell, he'd be even worse, since the guy doesn't care about anything other than growing a crop; and wouldn't care to learn things outside of that.
At the very least, he fits the saying my buddy loves to use - " ignorance is tolerable, stupidity is not".
