Schadenfreude And Mudita

Hera are some interesting explanation of certain emotions I found interesting:

Schadenfreude is enjoyment taken from the misfortune of someone else.

Envy is unhappiness in another's good fortune.

On the other side there is:

Mudita, "sympathetic joy" or "happiness in another's good fortune,". It is cited as an example of the opposite of schadenfreude.

Pity or Compassion, is "unhappiness at another's misfortune",
