Schadenfreude breaks down as such:
Schaden - damage & freude - joy
Yes, it's a little twisted & can be pretty heartless at times but that all depends on the person. Most people are pretty good at heart and it's all in fun. This is the one word that I remember most from my highschool years. I took German for 4 years & Herr Geissenhoff was a living example of Schadenfreude. Come to think of it, teenagers are a whole other example of Schadenfreude! Most of them are more on the twisted side of the meaning than the fun side though. Regardless of how others view it, I for one love and embrace the word for it's twisted but fun side!
