how you think soaphead might affect pecola ?

Just as Pecola associates whiteness with purity and beauty, Soaphead associates whiteness with purity and the innocence of children. It's no accident that when he speaks of young girls he has molested in the past, he refers to their "white laughter." Soaphead would be just as vile and repugnant to Pecola than any other little girl. Pecola actually does lose her sanity.
