Love or to be loved?

In Shakespeare’s King Lear, the value of love sees by Lear is measured by the utterances of his three daughters rather than their actions. In act 1 Scene 1, Lear has divided the kingdom to his three daughters. Lear first addresses his two eldest daughters, asking them to express their love for him before they and their husbands will receive the land he has allotted for them. Goneril says she loves her father more than she can say. Lear thanks her and gives her Third Prize. Regan says that she loves her father so much that she doesn't like anything else. Lear thanks her and gives her Second Prize. Cordelia says that she loves her father exactly as a daughter should. Lear angry and disowns her, and banishes the Earl of Kent for speaking in her defense. First Prize is divided between the other two daughters. You can decide whether King Lear is showing early signs of mental illness (as his other daughters think), or whether he just wanted an excuse to give Cordelia the best share of the kingdom and she just spoiled it. As a father, Lear acted in such an improper way and he is like playing a childish game of asking his three daughters for words to flatter him in order to get good fortunes. In reality life, does this ‘childish’ game exist?
