You agree that there should be a military and a defense industry, but anyone working on weapons R&D is a malevolent actor (ie “making the world a much worse place)? This seems illogical.
The effectiveness of a military is tightly bound to its long term R&D armaments. Without highly effective arms, and proper training and tactics, casualties suffered by our armed forces in combat would be far higher (as the Russians are discovering).
If you accept that the military exists at least in part to protect you, then investment in arms development follows as an obligation to those sent into harms way on your behalf.
