Both sisters are motivated by their desire for power and do not care how far they must go to achieve it. They are dishonest to King Lear who paints a false portrait of their love for him, only then do they get the biggest piece of the divided kingdom. Along with land and power over England, both sisters betray their promised responsibility to care for their father. Instead, Regan and Goneril plan to reduce their father's remaining authority to satisfy their hunger for power. They disrespect King Lear by reducing the number of knights he is allowed to have and ultimately depriving him of shelter during a storm. They do not care nor are they concerned about their father's safety. King Lear, soon realizes their betrayal when he expresses his grief to Cordelia by stating "...for thy sisters, as I remember, have done me harm: thou hast any cause, they have not" (4.7.83- 85). This line in the play demonstrates the evil portrayal of Regan and Goneril, because throughout the play King Lear has done nothing to deserve their treatment, instead he gives them all the kingdom and power he possesses. Ultimately Regan and Goneril's lust for power leads to their downfall. Both charters want to marry Edmund, Gonerial goes so far as to plan her husband's murder and poisons Regan. Later Gonerial kills himself when he discovers that Edmund is dead and because he would rather die than face the consequences of his wickedness.
