The experience showed that players who embody the villain, are more willing to act like one in their real life actions, as it is demonstrated when it comes to pour either chocolate or chilli sauce in a player's food. It is proved that the players who embodied the hero tend to pour more chocolate in other's food whereas, the ones who embodied the villain tend to pour sgnificantly more chilli sauce.
