Is Katherine Tamed OR Not

Even thought, I agree that Katherine has had a turn around at the end of the play, I don't think that Katherine is fully tamed. First, Katherine is human and humans will always get angry on touchy subjects. For example in Act 5 Scene 1 Petruchio says "Kiss me Kate" and at this subject Kate fires up, and starts disapproving. Also I think that Katherine still has the fire of the "shrew" in her, but is afraid to show it because it might cost her (like rips in dresses, no tender meat, or no warm comfy bed). So overall I think that she is tamed but just not fully tamed. 

The Shrew is Still There...

Like Ben Myer's Said: 

"By taking away Necessities such as FOOD, WATER, AND SHELTER...This can break any person down"

And I believe that is what Petruchio exactly did.
