There are no positive or negative effects from pressing this button.

You know you want to. I mean, you can't not press it now you're here. Everyone's watching you, waiting, to see what kind of person you are. To see if you're the button pressing kind, or uh... I guess.. the non-button...pressing...kind. Your whole life has come down to this moment, this is what you trained for, this is how it begins, and this is how it ends. The choice you make here settles the fate of the universe.....But you know you don't HAVE to press it.....but you should.....do it.
