13. I vote to have an effect on who has power, not to authorize representation.

Even if I did vote with the intention of authorizing representation, you are still mistaken to think that I would be responsible for anything that representative did in office. I don't authorize unjust wars, for example, even if I vote to have a representative in Congress or a commander in chief. In law (and in ethics), the liability of the one who authorizes agency or representation for the actions of the agent or representative is limited to those actions that are within the scope of that agent or representative's authority. Unjust actions, unless expressly authorized, are understood to be outside the scope of that authority.
