At the end of act 4, scene 1 in Petruchio's soliloquoy, what physical deprivations doe Petruchio plan for Kate? and What change of tone is conveyed in Petruchio's use of the phrase "reverend care"?

He won't let her eat or sleep. He thinks he is caring for Kate by depriving her thus making her more "obedient". Really what he is doing is quite cruel. His change in tone is that he is doing all this out of kindness but somehow this doesn't seem all that kind!
