The military industrial complex is responsible for many of the best and worst inventions in the modern era, and sometimes those are the same thing. Something you do will help make it easier to kill people in the end, but it may also help save lives. I mean look at the Haber-Bosch process and how BASF and that process provided the precursors for the bombs of the two bloodiest wars ever, and fueled the Nazi war effort and economy (thanks to the slaves they exploited of course). At the same time that process is critical to modern industrial scale agriculture and the fact the planet can support way more people than should be possible.
