Graphical representation of intersection among prosocial acts and acts judged as supererogatory, obligatory, suberogatory, or impermissible. The subset of actions that are prosocial are expected to intersect with the subsets of actions that are deemed supererogatory (i.e., okay to refrain, should do), obligatory (wrong to refrain, should do), suberogatory (okay to do, should refrain), and impermissible (wrong to do, should refrain) by most or all people.
