Agreed. It's firmly an "ends justify the means" ideology, reliant on accurately predicting future outcomes to justify present actions. This sort of thing gives free license to any sociopath with enough creativity to spin some yarn with handwavy math about the bad outcome their malicious actions are meant to be preventing.
It just doesn't. It's about how to make the most from altruism. It's got nothing to do with predictions. If you make enough to pay some people to work in a soup kitchen, don't quit your job to make soup. It's nothing more.
