If I was a samurai warrior, who swore to protect my daimyo and the emperor, whose side would I pick if the two of them are going to war against eachother

     When I became a samurai warrior, I swore to protect both my daimyo and the emperor. Now, the two of them are going to war against each other. Both of them want me to fight for their side. Bushido, the samurai code of rules, states that I must protect them both. If I fight for the emperor, I will have to fight against the other samurai warriors of whom I used to work with. But if I fight for my daimyo, the emperor is sure to be over thrown, and I don't think I want that. He's just a figurehead, and he hasn't done anything wrong.
     But, I think I would choose to fight with my daimyo because he has more weapons, warriors, and he would be more powerful in a fight.
