Practically it is impossible, I agree but everyone being dead leaves nobody to suffer. Logically this seems like a simple yet functional solution.

It's simplicity on a conceptual level is what I believe attracts so many to the idea.

I didn't expect anyone to actually consider mass genocide being a serious practical solution.

I have no idea what this Thanos thing has to do with it either.

Also I have no idea what maths has to do with this. I never mentioned an equation. Just that by everyone I indeed meant everyone. This is a theoretical solution. If humanity insisted on being practical all the time we would probably not have ended up with things like topology.
