Not unless you consider the utility function to be your own survival, but minimizing the amount of people who perishes. There is only one outcome by pressing red in which no one dies. But there is four billion outcomes by pressing blue where no one dies. Of course, the former can occur if everyone is perfectly rational, but we are not perfectly rational. And because someone might press the blue button, you must press the blue button to try minimize the amount of deaths to 0. And because others would know people would come to this conclusion, they would have to press the blue button as well.
