BRB . Going to get my jean jacket out and turn on some GNR . <| sep |> Especially when it ' s verbal abuse and hate speech <| sep |> The reason Batman paused on Martha ' was because it was inconceivable to him that KalEl had anything resembling a human life . Before Clark spoke , he was , to Batman , a nearly invulnerable alien who could influence and intervene in human affairs with impunity . When Superman asks about his mother , Batman suddenly becomes Joe Chill , about to shoot young Bruce and create a trove of grief . After hearing that , he cannot kill him . At least , that was my take and I think that it made sense as the reason Batman would decide that he was wrong because the alien wasn ' t such an alien after all .
