In Julius Caesar, Shakespeare presents the last view of Caesar in Act III scene i. How does Shakespeare portray Caesar as he is about to die?

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.
