Whatever your thoughts about Caesar during his life, whether you think of his a megalomaniac who really has such an overwhelming sense of his own importance that he deserves to be assassinated, I think all must agree that Shakespeare endows his character with nobility in the way that he meets his grisly end. His final, famous words, "Et tu Brute? Then fall Caesar," suggest a mature acceptance of his own death that perhaps surprises us given the way that he talks about his own power and his own sense of himself. His final words could be construed as a realisation of how far he has gone in terms of his power and megalomania and perhaps even go as far as to accept that his death is a natural consequence of the limits of power that he has trangressed. The fact is that Caesar never appears to be nobler than in his final words.
