Avital ronell's walk through a path in central park is related to her comments of a path to living an ethical life. what are her basic presumptions on ethics?

Her basic presumption is the majority of people do what we considered as ethical for the purpose of making ourself feel greats.
For example, when you walk on the park and give some cash to the homeless and felt 'i did great because i helped him'. You're basically give the money not because you care about the homeless but because you seek false motive in doing ethical acts.
