Schaudenfraude From Recent Super Bowl

Schadenfreude is the joy of harming others. For example, if someone acts cocky and then has a mishap and you can't help but smile. So you think to yourself: "He deserved it, the right person was affected"... that is the definition of schadenfreude.

So in this case you watched KC getting all the advances on 50/50 decisions by refs, to win close games all season and suddenly in Super Bowl there is one opponent, dont fool around and gave them a 31:0 in first half you feel joy to see KC fall apart suddenly. So the OPs wording was right.
