On that same note, if you vote a President into office, and he initiates an unjust war, does that make you innocent, or are you just as culpable for having voted him into office? And, if you believe you are innocent, than is that President innocent, because he's not actually fighting the war? And, if you believe he is guilty, does that make a soldier innocent, for volunteering to be in the military, and thus participating in the war, "while" it is ongoing?
Exactly what you define to be innocent can be stretched to unimaginable levels, but so too can you stretch culpability.
