How does King Lear react when he sees Kent in the stocks? What does this reaction indicate about Lear's character?

Lear is shocked and appalled to see his servant in the stocks, but even more surprised that anyone would dare to treat his servant in such a way. Lear demonstrates his caring side when he demands to speak with Regan and Cornwall to confirm their part in Kent's pumishment, but they refuse, illustrating Lear's loss of command.
