It did crash twice, but not because it is structurally unsound. And not because it is unstable.

edit: Also, when you say the engines were put "on top of the plane" it makes me question if you've ever actually seen a MAX 8.

You should stop posting about issues that you are completely clueless about. I'd point out where you're wrong, but in short: everything.

Well, the plane did crash twice. Everything else seems wrong though.
