I would replace it and center it. For a few pennies, it's not worth playing with it. I have a box of them left over (they come with a lot of brakes but I do not use them).
It shouldn't be like that- that appears to be a recessed target (not a flat) crown- and assuming that's the case the washer taper should have mol accurately self-centered.
It wouldn't surprise me if there were an accuracy issue due to the gases being forced off-center (due to the crown now being off-center by being partially obstructed) behind the bullet and pushing the base off to one side.
I can't tell for sure- but it appears that the uneven torque is forcing the brake a tiny bit out of concentric with the bore as well- which is another problem if that's indeed the case. Threads, by design (even class 3) have "play"- and brakes need to be torqued perfectly square to the barrel shoulder.
