I watched the game yesterday and at one point said to someone, "why don't they ever show German fans cheering or crying tears of joy?" -It was all Brazilian fans crying, even small children with their dreams dashed away. -TV loves this stuff.
Schadenfreude isn't random in the case of futbol. There is legitimate hatred involved here, between teams and players and countries and coaches. Sure, it's funny when a toddler drops her ice cream cone and starts to cry, that's schadenfreude as I understand the definition of the word. But this is purely about the vanquishing of one's enemies and relishing the lamentations of their women. :D
Besides, fierce competition makes for a better game. Even if your side loses. Probably. I think.
