Does Sophocles take a stand in favor of either side (Antigone or Creon) in Antigone? How?

It sure seems to me he does take a side.  How Sophocles
chooses to characterize each of the principle players  tells me he sides with
Antigone.

Ismene is weak and submissive, accepting what is
without question or action. 

Antigone is strong and
passionate about doing what's right, whatever the
cost.

Haemon is an obedient son; however, once he
recognizes his father's unwillingness to bend in the least for those who matter most to
him or to see reason, he sides with Antigone.

Creon is
arrogant and prideful--unwilling to bend even for his neice/future daughter-in-law and
his nephew.  Ego and being right matter more to him than anything
else.

In the end, all three suffer for their actions;
clearly, though, the root of all these tragedies is Creon's pride.  His law (state law)
is unjust in that he decrees it out of pride and personal revenge.  That tells me
Antigone is on the side of righteousness, according to Sophocles, because she chooses
moral law over an unjust state law. He clearly outlines the consequence of such
disobedience, but he is most sympathetic, I think, to Antgone's
cause.
