The only standard that would

The only standard that would matter is the one you decided upon for yourself, so long as it did not violate natural law (the NAP).

I don't think self-defense is the same thing as rebellion, self-defense is used to stop aggression. It becomes immoral when it changes from self-defense to "hitting back". Hitting back would be considered rebellion in my mind and would be immoral.
