While one could make an argument for or against Captain Beatty having wanted Montag to kill him, one can infer that Montag's assessment is correct when he says, "Beatty wanted to die" (Bradbury, 57). Captain Beatty is a rather enigmatic character. He is extremely well-read, yet he enthusiastically supports censoring literature. In an earlier discussion between Captain Beatty and Montag, Beatty tells Montag,
Any man who can take a TV wall apart and put it back together again, and most men can nowadays, is happier than any man who tries to slide, rule, measure, and equate the universe, which just won't be measured or equated without making man feel bestial and lonely. I know, I've tried it; to hell with it. (Bradbury, 29)
This comment is significant because it indicates that Captain Beatty once searched for knowledge, but he was not able to find the specific answers he was looking for in life. Beatty became jaded with intellectual pursuits before deciding to fully support the fireman structure. Essentially, Captain Beatty both admires and despises literature. This disconnect in his character could explain Montag's reasoning, which is that Beatty wanted to die. One can infer that because Beatty was unsuccessful in finding answers for his own life, Beatty no longer wants to live, because he believes he will never fully comprehend the universe.
