It was Kaneki who stabbed Shuu. You can tell from the shadowed out panel of Kaneki's face, as well as noticing that Kaneki has his Kagune out behind him on the bottom right panel.

I don't think he did it out of pure spite. By the looks of things, he's doing it to make sure Tsukiyama doesn't get involved with his confrontation with Eto.
