A different sort of antonym for Schadenfreude?
Solution 1:
Compassion: "sympathetic consciousness of others' distress together with a desire to alleviate it".
Solution 2:
Commiseration: a feeling of sympathy and sorrow for the misfortunes of others
I think there is a subtle difference between commiseration and compassion, where commiseration involves actually feeling miserable along with the other person while compassion aims more toward the desire to alleviate it.
