If your desire is to fulfill the ideal of not hurting anyone, then do as you wish. But only if that desire is truly yours. If you fight of your own free will, any resulting crime or punishment is of your own making. Accepting them is a part of that ideal. But if that desire was borrowed from another, the ideals you uphold are mere fantasies. You need a reason for fighting. But that reason must not be your ideal. If you fight for your ideal, you can only save your ideal. That doesn't entail helping others. A reason to fight is the desire to save something. At the very least, it is for you. But salvation by the hands of others is not salvation. Such salvation is like money. When used, it passes into other's hands. It's true that you can probably achieve your wish to save others. But there's no hope of saving yourself in doing so. You will repeat the cycle until you die, still clinging to ideals that are not your own. That is why your ideals are meaningless. Nothing comes of helping others. In the end, you can save neither others nor yourself. A life of a lie.
