Poe still gave the order, though. Even if it was supposed to be a kamikaze run, the plan was off by that point.
It wasn’t supposed to be a kamikaze run. Finn was the one who decided to go for a kamikaze run against Poe’s orders (after Poe ordered the retreat), so that he could save everyone. But Rose stopped that, theoretically dooming all of the rebels except for her and Finn.
