It's never acceptable to target civilians. It violates the Geneva Accords it violates the international law of war and it violates all principles of morality.

You can hold yourself back from the sufferings of the world that is something you are free to do and it accords with your nature but perhaps this very holding back is the one suffering you could avoid.
