My own view is that if / when the Max returns to the skies, it will be just as safe, safer maybe, than anything else.
But that's not really the point, is it?
Airlines are businesses, and they need customers. If the customers are scared to fly on the thing, it doesn't really matter whether their fears are well founded or not.
I'm sure Boeing will find a way to convince the FAA it's safe.
Convincing the public's going to be a bit more difficult.
