The generally accepted rules of war are hard to apply to something like the issues Kaczynski addressed because it's not a traditional war. Some civilians in places of power can do more damage than any individual soldier. When the war is fundamentally different the rules have to change with it. I think his problem was not going after anybody high up enough to actually be culpable. His targets weren't exactly the most effective. Going after computer store owners and graduate students is a lot less justifiable than going after energy company CEO's and corrupt politicians.
