It seems that schadenfreude is also translated as “misery loves company”; I suppose that’s true, but I’ve always thought of it more as the sarcastic “Couldn’t happen to a nicer guy!”. It’s the guilty, bitter-sweet pleasure of delight in the misfortunes of others.
But the thought occurs to The Curmudgeonly Progressive that schadenfreude pie is addictive, and highly destructive. It causes congestive heart failure, radical personality changes. Your heart turns into a stone, and leads to maniacal cackling, making the user unsociable, and leads to social disengagement.
Schadenfreude pie is best enjoyed in tiny bites, and must be followed by copious amounts of the milk of human kindness. Do not indulge too frequently, and offset it by humanitarian exercises.
