catcher and the rye

was it just me or was catcher and the rye about a character that had an arrogant sense which created a cockiness that he negatively infected on others, then one day become mentally challenged and sees what the world is like when you can only function to the others a certain way despite what your mind may think? he then becomes enlightened and understands that one cannot be judged for even how he acts because how he acts may not be who he is.
