Sometimes, there is no perfect action or sinless choice. Do you permit an evil government to continue or do you fight that government?
Romans 13:1 "Let every person be subject to the governing authorities. For there is no authority except from God, and those that exist have been instituted by God."
If you are going to oppose the evil government, then you would be following Martin Luther's advice to "sin boldly". When there is no perfect choice, make a decision and follow through.
Since when did opposing "evil governments" become sinful?
