explain how the theme good vs.evil was developed and the outcomes revealed in pygmailon? what is shaws about mankind?

It's difficult to use the terms "good and evil" in this. Much of what we might consider bad or good is couched in themes of social class and misogamy of the time. The elite misusing the poor for amusement or experiment certainly carries an offensive value system. Men molding women into something that pleases them is also rather offensive although still done to this day. So "good and evil" become socio-economic and gender traits that are subject to various interpretations in various time periods.
