There are some people who might not want more genocide, a climate cascade causing a mass extinction event, a psychotic economic system, a food system torturing 2-6 trillion animals to death a year and enslaving 2-4 trillion animals in torturous conditions a year, unsustainable pollution, biosphere degradation…

They might instead want to help in the long fight towards an ethical civilization instead. It may be a long defeat, but for those who won’t cross the ethical lines listed above, doing the right thing (even if they lose) is better than being culpable in actively supporting those who are making the system more evil. The difference between +9+9 and +7+6 is real, but for some the ethical lines they won’t cross is below +7+6.

If Stalin is the lesser-evil compared to the greater-evil Hitler, then there’s still the option to vote for unpopular Gandhi and maybe start the process where people realize they don’t have to be culpable in actively supporting Stalin.
