If everyone has to press a button and is not allowed help to do so, then there's various people who may not be able to properly choose and presumably, half of them will hit the blue button. There's blind and colour-blind people as well as young babies or even people in a coma, which raises the question of whether a button is pressed on their behalf. One way round the dilemma is to make it optional as to whether to press a button and in that case, it would seem to be sociopathic to press the red button as that increases the chance that blue button pressers get killed. The best choice in that circumstance is to not play the game which is surely the moral choice too.
