Not true for all aircraft. On some types they are used either to provide stall identification and/or to prevent excursions to high AOA where a deep stall IS a concern, but they are set to fire post CLmax (i.e. with the wing stalled) in the interest of maximizing aerodynamic performance. But as the A330 doesn't have them anyway thats tangential.

That really depends on the details of the stall location and progression. I can conceive of it doing as you say; I can also conceive of it being relatively stable/controllable. It all depends where the wing stalls, how much of it stalls, and how sensitive it is to AOA shifts in terms of progression.
