Joker yes. Sakamoto yes, but specifically through the lens of focusing down on the awful shit Shido has pulled and how he has to be stopped at any cost. Takamaki will hesitate, but eventually agree with Sakamoto.

Kitagawa will take his time considering. Makoto will be sure to remind him that this doesn't erase the things he's done. Futaba will be conflicted, but listening to the others will bring her around.

Haru... will want justice for her father and all the other people Shido trampled over for his ambitions. She'll be willing to put Magpie's sins aside for that purpose. And however much Morgana might object at first, in the end he'll go with whatever Joker decides.

...That's my assessment, at any rate. Of course, it's been years since I last interacted with those of them who aren't here.
