Alice in Wonderland... and morality?

I'm not going to get into a full review of Tim Burton's new Alice in Wonderland movie. But there was one thing that particularly struck me which I'm going to point out.

The White Queen (played by Anne Hathaway as either ethereal or disconnected-- I couldn't decide) has made a personal vow never to harm a living thing.  However, in order to oust the evil Red Queen from the throne, someone must kill the Jabberwocky, a stereotypically draconian beast which is the Red Queen's greatest weapon.  The White Queen obviously can't do it herself, so she has spent the last several years searching for a champion who will kill it.  The ancient prophecy says that this champion will be Alice, who has forgotten that she's been in Wonderland before.

This is the basic plot of the film.

It's the White Queen's vow on which I care to focus.

See, while she's vowed not to harm any living thing herself, she seems to have no problem with killing or war in general.  She leads the army into battle, but cannot participate.  She has all the tools necessary for reclaiming her throne, but cannot act.  And she seems to have no qualms about putting severed human fingers into a potion she makes.

My point here is that she seems to be a bit hypocritical.  It's almost as if she's bound to this vow against her will.  We're never told why she made it or to whom.  Only that she's sworn not to harm anything.

Now the question arises: if you have no problem with living things being harmed in war or otherwise, why vow not to do it?  I'm not going to make a vow not to eat meat.  You know why?  Because I don't have a problem with eating meat.

Not to mention, accessory to a crime is punished as a crime itself.  Supporting someone who does something you believe is wrong is also wrong.

So, White Queen, your vows don't make much sense.
