Cruel? Yes.
Somebody who is so ill as to not be able to deal with their bodily misfunctions is hardly the person to be punishing for that failure. Should I have bitched at my dying mother for not cleaning up after herself? Following this logic, that should have been the case. Worthy? Hardly. My mother was not a nice person, but she at least never punished me for being ill with the flu. Her terminal illness was not pretty but I was glad, at least, to be able to clean up after her. Why? Because caring for the sick is a worthy thing to do. It's hard to fathom how this kind of cruel punishment imposed on a sick child taught compassion or self-reliance for that matter.
Poor mishca.
I'm up not sleeping after nightmares. Fun.
