An airplane is trimmed to fly at a particular angle of attack, hands off; that's an inherent feature of the pitch stability mechanism.

If you don't apply back pressure then the AoA won't change, and since stall depends only on AoA you won't ever get any closer or further away from a stall, no matter what manoeuvre you fly.

If you enter a turn hands off then wing loading increases due solely to an increase in airspeed. You're no nearer or further away from a stall though because without exerting a stick force you haven't changed the AoA away from the trimmed AoA.

This is what happens in a spiral dive.
