One thing I rarely see mentioned is that John bullied Stu on the regular and if Paul was bullying Stu, it’s often because he was joining in on it.
“Though utterly self-assured in his work, Stu was full of personal insecurities about his appearance and small stature. And even with so impressive a friend, John could never resist homing in on insecurity and frailty. ‘He generally toyed with people,’ recalls Bill Harry. ‘If you stood up to him, he respected that and wouldn’t try it on again. If he detected any weakness, he took advantage. Stu was very mild and gentle, and John would put him down verbally in a way he never did other people in our circle, especially not Paul.’”

The Beatles had lots of little arguments amongst themselves, but nothing serious. It was mainly Stu and Pete, the relatively new boys, being picked on by the rest. Stu took it to heart, but Pete didn’t seem to notice. It all passed over his head.

They argued as usual amongst themselves, but most of all they picked on Stu, the newest member of the group. John, George and Paul had been with each other long enough to know that rows and arguments and criticism didn’t mean much. If it did, you just argued back.
‘We were terrible,’ says John. ‘We’d tell Stu he couldn’t sit with us, or eat with us. We’d tell him to go away, and he did.’ At one hotel they stayed at, a variety show had just left. There had been a dwarf in the show and they found out which bed he had slept in and said that would have to be Stu’s. They certainly weren’t going to sleep in it. So Stu had to. ‘That was how he learned to be with us,’ says John. ‘It was all stupid, but that was what we were like.’
The Beatles, Hunter Davies
George and Paul appear to have been slightly jealous of Stu and his influence with John, not that outsiders could see how much John admired Stu. John picked on Stu all the time and hurt him when he could. Paul, following John’s lead, also began to pick on Stu, even though he was interested in art and, like John, was getting from Stu a lot of new ideas and fashions.

PAUL: It wasn’t just me. Legend so often divides these things neatly down the middle: John was hard, I was soft; John loved Stuart, I didn’t. But John was perfectly aware that Stuart couldn’t play and it wasn’t just me telling Stu to turn his back to the camera, it would often be John saying that. We used to ask him to turn away and do a moody thing looking over his shoulder so no one could see that his fingers weren’t in the same key as the rest of us. It wasn’t a good thing for a group to have someone who was such an obviously weak link. I think John felt a sense of relief when Stuart stayed in Hamburg. In a way, it was actually very convenient. Nobody wanted to sack him; it would not have got to that because of his personal friendship with John. But nobody was that sad to see him stay in Hamburg. It seemed right that we all had to move on and I quite easily got into bass.
You can’t help it, if there’s somebody in the group who doesn’t click. Like Stu. Stu was a great guy, a lovely guy, and I didn’t understand him, it’s true. There’s a lot of people in my life I haven’t understood; I’m not the world’s most psychic person. I make a lot of mistakes, and I misread people, I’ve read a lot of stuff about Stu since that I didn’t know about; I was taking him all wrongly. But it certainly wasn’t just me who was getting at him, everyone had their little goes. But I suddenly come out as the ‘go-getter’ and the ambitious one in the group. And John’s portrayed as the kind of nice guy who always falls into situations.
Plus the previous quote from above:
Sutcliffe realized the situation was untenable. There was no place for him on that stage anymore; Paul - and even John, by his neutrality - had made that absolutely clear. Stuart moped around for a few days, disillusioned with the band and with himself. The constant insults, the humiliation - he’d had enough.
If Stu could feel that humiliated and affected by only Paul insulting him, then that would indicate that Paul did have a lot more power than is typically assumed. Or, more likely imo, is that it was John + Paul bullying him together that made Stu feel humiliated (just check out my other quotes about them being a nightmare duo). As Mick Fleetwood said:
They were a team, a rhetoric team to say the least. As you can well imagine, John Lennon on form, in form, and Paul as well, it was catastrophic. I mean if they wanted to rip you apart, you were a dead duck… I thought, I would never want to get caught between those two, ever. You know, count me out, they were on top, sharp as tacks.
That’s about how they treated GEORGE btw so imagine how bad they could have been to Stu, who Paul actively disliked and while John was in his peak schoolyard bully phase.
It’s typically portrayed as John and Stu ganging up on Paul, who was left behind by them and could only seethe impotently at Stu taking his place as John’s bestie. But John was clearly playing both sides and it seems ultimately he saw Paul as more of an equal- or more of a threat- and triangulated him and Stu against one another.
