If you can see well enough to identify and fire on a target, it is a virtual guarantee that you have enough light that muzzle flash is not going to be a problem. I have fired numerous guns in the dark. The only one that had enough flash to effect my vision, even a little, was a 18" barrel 12ga firing deer slugs. Even with that one, I was left with a "glare" in the pitch black that was a complete non-factor as soon as I got to a lit area.
Still happily answering to the call-sign Peetza.
The problem, as you so eloquently put it, is choice.
He is no fool who gives what he can not keep to gain what he can not lose.
