Who does George want Beneatha to behave? What does he want her to give up? Is this selfish of him? Why or why not?

George wants Beneatha to behave like a silly girl without a thought in her head. He wants her to be an armpiece, to look good, be well-mannered, and give a good impression. He does not want her to be a deep thinking young woman, who is willing to ask questions or take a stand.
