Kazami was trying to Kouichi because, at the end of the day, he's a coward and he couldn't ever make a move on Yukari, so he tells himself he would've had not Kouichi been in the way. He's purely out to avenge some imaginary slight because that's easier than admitting he was himself not up to snuff.

Izumi is trying to avenge her friends, which, as far as she knows, dovetails nicely with ending the Calamity. You could take her line as having the unspoken "Even if she's not the Extra she sill killed my friend." She still thinks Mei murdered Takako and then, just to be extra cruel about it, was getting ready to desecrate her body. Even if she isn't actually the Extra, she still deserves death because she's a psychotic little monster, as far as Izumi can tell.
