I get what you're saying, but it's all comparative. Karma isn't going to come for him, his situation is far worse. He has to live it.
And that's why he's lashing out.
Think of how Jordan would manufacture slights in his head before games just to motivate himself. That's 50. It's just that his constant "acknowledge me" games have never backfired this badly. Turns out that he ran into a bigger fish (

) and got ravaged because Puff is a dope fiend degenerate that's been on a Rick James kinda run for so long, and the guy specializes in snaking people's girlfriends out from under them.
50 will do all the promo and talk shows and whatever else and pretend that making money off of Puff's conviction is somehow any kind of get back...and it really isn't, not compared to the day to day eternal shame 50 has to regurgitate and swallow every time he even thinks of his child.
This Netflix doc is basically whataboutism writ large...and it's not going to work. Puff having to sit down didn't make 50 any taller.
