Last Diabolical Achievement (Spoilers!)

Does anyone know what combination of stats is required to get the No Rules achievement? Every time I try, I end up causing a nuclear war, which doesn’t unlock the achievement.

I think you need a combination of high pragmatism and selfshness.

For some reason, I can’t finish with a Pragmatism score higher than 68. Even being too long in Nautilus’s presence lowers my score below 70, even if he doesn’t like me.
