Yes and no. Thanks to Christendom, we have the ethic that we ought to help the powerless. However, the choosing still lies altogether with the person in a position of of power, and if that person says 'no' and walks away, there is nothing the powerless person can do. Even if a group of ethically superior people gang up against him and make him help because he ought to, it's not because of the powerless person but because of someone else's.
