How to fix a cracked wall when it's not seriously structural?

What do you think?

The Berlin Wall fell for a reason. It would be foolish to consider trying to rebuild it - and all it represents - today.

Use spackling paste and sand!

Really? Lol

I don’t think this is the best solution. This looks like a serious structural crack. If you look inside the wall structure the cracks are deep. This is just like when some with serious acne does make up.

Simple and logical wall fix
