I don't think I've ever experienced schadenfreude. As in, I'm not even sure what that emotion is supposed to feel like, from the inside. I get the impression that the few people I've said this to think that I'm lying about it for signalling purposes.

Is it common just not to feel schadenfreude, like not ever, for any reason? Lately I've started to wonder if I've been committing the typical mind fallacy on this.
