He underestimate the God of Death (fake), like other students. For the fight with Karma, I think the comment on his height irritated him. (he wanted to buy some centimeters if he kill Koro-sensei ... like Kayano wanted to buy a larger bust, to kill two birds with one stone - I don't think she was lying about this)

But yeah, he is still naive, particulary because he can't solve everyproblems with assassination skills.
