How does "The Scorpion and the Frog" relate to integrity?

There is much in way of integrity shown through this
fable.  The most dominant display of it is through the frog's actions.  Understanding
the risk of death at the sting of the scorpion, the frog is able to overcome his own
misgivings and do the honorable thing in shepherding the scorpion.  It is his integrity
that compels him to do such a thing.  Additionally, it is his integrity that leads to
his death.  For his part, the scorpion usually gets the lion's share of criticism.  Yet,
I think that the scorpion also demonstrates integrity in that he fully accepts
responsibility for his actions when the frog asks him why he stung him despite his
help.  The scorpion does not hide from the fact that it is in his nature to sting and to
kill.  This is who he is and what he does.  There is much in the way of integrity
offered in such an admission.  The scorpion wishes to be something that he is not, which
is why he offers so much in way of justifications as to why he will not hurt the frog. 
Yet, in the end, the scorpion cannot evade his true nature, the essence of his
identity.  This openness and this acceptance reflects integrity.  The integrity of both
animals ironically contributes to their deaths at the end of the
fable.
