I mean what a POS. Abandoning his wife and kid to run off with Yoko Ono. According to Paul McCartney the song Hey Jude was written to cheer up John's son Julian who clearly seemed to be struggling with the divorce.

So what does John Lennon do? He loves the song because -surprise- he assumes it's about him! This motherfucker has the audacity to think it's Paul's way of greenlighting his relationship with a homewrecker.

So how does John Lennon actually treat Yoko Ono when they're together? Apparently he hits her, quite a bit, and is even more mentally and emotionally abusive. Just like he was to his first wife Cynthia, and even to his fling while he was with Yoko.

The icing on the cake has to be when he dies. Even after his death he screws over his son. Julian had to buy the fucking letters he wrote to his dad because Yoko just.....didn't think he should have them.

Tl;dr The guy who loved to bleat about world peace and shit was a wife beater, serial cheater, treated his band mates like fucking doormats, and I'd say he was a shitty parent but that might be putting it mildly. Fuck John Lennon.
