Schadenfreude - taking pleasure in another's shame or misery - is clearly a terrible and vicious way to behave. The noblest among us avoid it at all times. Most of us are not that noble. I try to be, but I confess, dear reader, that this is one of my vices.
Personally, my joy at the Flyers' loss to the Devils tonight could only have been sweeter if a hideous error by two Flyers had resulted in what was, essentially, an own goal by the Flyers' goalie. </sarcasm>
