Why does captain beatty want to die?

I believe Captain Beatty wanted to die because he was struggling with an inner conflict. Through all his quotations throughout the novel, we can conclude that he was very intelligent which made him not fit in into society. Beatty probably became a fireman because books caused him his problem (made him smarter) so he thought he could get rid of the knowledge he had by getting rid of books. Through this, we can assume he was "the boy in your own school class who was exceptionally 'bright', did most of the reciting and answering while the others sat like so many leaden idols, hating him. And wasn't it this bright boy you selected for beatings and tortures after hours? Of course it was. We must all be alike." (p61) The only memory associated with knowledge and information is that he was bullied for being that "bright boy". This makes him believe all knowledge is bad for him making him want to get rid of it. What he doesn't understand is that he will never be able to rid himself of Words so he took the easy way out by killing himself.
