well, as far as I could understand it, our voting system does not claim the power to decide the fate of humanity. It's a tool that aims to help administration of the budget, pure and simple.
You are right. This is the case. You are allowed to administrate the budget, and you can do it for whatever reason. Pure and simple. Including of course some reasons that are about to decide the fate of humanity. Its up to you to decide, and you are allowed to spend your budget however you wish.
If you believe that you should not be allowed to administrate the budget for some specific reasons, then those reasons should be written of course. But as far as I know, currently there is not any restriction on that.
