Why do all the protagonists of these kinds of stories become proud and arrogant after gaining a puny amount of strength? Is this subconscious thinking of these authors?

One of the worst MCs I Have ever read about. ZERO IQ, Batshit lucky, everything was spoon-fed, lazing around always. If by any means this was real he would die a gruesome death over and over.

How can a warrior with a gap of two rank differences fight? The author specifically told many times the protagonist did this time after time even though he was too weak. Monotonous fighting without any intelligence. The story development is too poor.

Why is this MC so stupid and arrogant? Always bites more than he can chew. If not for the story plot he would die more than a hundred times. In the fight against the zombie he didn't even think of fire in the first round which can even melt divine steel.If it is a little less arrogant and a little bit intelligent it would be far more interesting.
