They could also easily just desire different things (“have different utility functions”). This is the basis for gains from trade, and, more germane to this example, political parties.
If Effective Evil thinks the most efficient way to do evil is assaulting people’s eyeballs with dust specks, and I think the most effective way to do evil would be increasing torture, I can use the money they give me to engineer aeroplane dust distribution technology to reduce torture. If they think 1000 specks equals 1 minute of torture, but I think 10e9 specks equals 1 minute of torture, there is a wide latitude for us to make a trade where I reduce 10 minutes of torture in expectation, and they get more than 10,000 specks-in-eyes. Their conception of evil is maximized, and mine is minimized.
