What are the differences between Claudio and Hero in Much Ado About Nothing?

Although initially these two characters seem similar in
terms of their shyness and their youth, it is clear that as the play progresses we
question Claudio's character more and more. Hero appears to be the stereotypical figure
of a meek, mild and submissive woman. Note the way in which she utters but one line in
Act I scene 1 for example. Her goodness, purity and innocence are obvious. However, we
begin to suspect that there is something rather disturbing about Claudio with the way in
which he is so quick to accept the "proof" of Hero's infidelity and especially the way
in which he publicly chooses to shame her at their "wedding." He never questions the
"proof" that Don John has shown them and chooses to damage both Hero's and Leonato's
reputation in public in the most overt way possible. Note the words he uses to do
this:

But you
are more intemperate in your blood

Than Venus or those
pamper'd animals

That rage in savage
sensuality.

It is hard to
escape the conclusion that Claudio shows great cruelty and viciousness in the way that
he denounces his bride-to-be, and a readiness to believe the worst that speaks of a
jealous disposition and an obsession with honour. Whilst the two do get back together,
we are left with the rather unsettling thought that Claudio has shown himself to be
unworthy of his bride.
