@Frondeur @Griffith @LukeAlmighty @aceattorneybot @BowsacNoodle @karna Fine. Let's go ahead and proceed by drawing out the matrix, then.

There's 7-8 billion people in the world. Your vote does not matter in any meaningful way. Either most people will press blue or most people will press red.

If you press red, then either nobody dies or everyone who pressed blue dies. If you press blue, then either nobody dies or everyone who pressed blue *plus you* dies.

Your choices are functionally "maybe I die" or "I definitely don't die." Yes, each square is going to have varying utility for each person, but you have two choices, and there is only one difference between the two choices. Game theory applies unless you want to account for the astronomically small probability that your vote mattered.
