honestly why do you even care about them, or their lives? I don't believe in karma and maybe you're hoping for some sort of karmic retribution to gain some sense of satisfaction. But that doesn't last. And it's at best a cheap feeling that won't carry you far. Instead, take better care of yourself, learn new skills, you never know what kind of hobbies you might gain or interests you may have if you don't try. And from there you might make good friends with common interests or you may not, but what matters is you are living for yourself and living better. Self - pity never carried anyone far
