Not really. The best example of Schadenfreude (imo) is when you follow a sports team (probably not too many of you here on Lemmy), whenever the rival team loses you feel Schadenfreude. There doesn't have to be any kind of 'just-ness' to it, actually if the rival team losses unjustly (played better, but were unlucky) the Schadenfreude is actually greater.
Of course there are times when something bad finally happens to someone that deserves it and you feel joy from it, but I wouldn't call that Schadenfreude, more like 'Vergeltungsfreude'.
While 'Schadenfreude' literally translates to the joy of damage, 'Vergeltungsfreude' would translate to the joy of retribution.

Oh my god, yes. Your best victory is the victory of succeeding at something and moving the fuck on with your life if you can. People are shitty. Our environment is shitty. It is what it is. Keep trucking. I am a product of my environment, but I can control some of it. In my opinion, chasing your goals, time and distance is a solution for all social ills. Well maybe not all but I mean shit you gotta try
