why does everyone hate on Peter Pan??

I don't get it! why does everyone complain how mean he is? i mean yeah he was cocky but id get pretty cocky too if i could fly, everyone loved me, and im a 12 year old boy that kicks adult pirates butts on a regular basis. and so what if he regularly torments the pirates, pirates are criminals and hook is legitimately evil, he kills a few of his pirates for basically no reason, so as far as pan cutting off his hand and throwing it to the alligator is concerned, hook probably deserved it. Also, he always comes to the rescue, whether Tink was getting blown up by a bomb, or wendy was walking the plank or falling onto sharp rocks, he also saved princess tiger lily, and he didnt even know it would set the lost boys free.
