The　influence　of　social　class　on　prosocial　behaviour　has　long　been　a　focus　of　intense　research　interest.　The　present　research　involved　four　studies　that　covered　four　moral　exemplars　(villains,　victims,　heroes,　and　beneficiaries)　to　test　whether　people　of　different　social　classes　are　treated　equally　in　moral　judgements.　We　described　moral　events　experienced　by　different　agents　of　varying　social　classes　and　asked　participants　to　rate　the　morality　of　the　events　and　their　emotional　responses.　The　results　revealed　that　compared　with　the　low-class　condition,　high-class　individuals　had　an　overall　moral　disadvantage　when　they　were　regarded　as　villains,　victims,　and　beneficiaries.　For　the　exemplar　of　hero,　the　high-class　condition　was　no　different　from　the　low-class　condition　except　that　high-class　heroes　evoked　less　elevation　than　low-class　heroes.　The　results　reveal　that　people　hold　a　biased　moral　attitude　toward　individuals　in　different　social　classes.　©　2022　Asian　Association　of　Social　Psychology　and　John　Wiley　&　Sons　Australia,　Ltd.
