If someone told me I had to deliberately kill innocent people or go to prison, I would choose prison and it wouldn’t be close. I would also prefer to end my own life than do this.

I know it’s not this simple in matters of war, but if someone believes their government is systematically committing moral atrocities, it seems reasonable to consider civil disobedience as an option even if the consequences are severe.

You’re right that we in the US are lucky not to be faced with a choice like this (for now), but I still think it’s a choice.
