Great insight! Only thing I’d like to add is that all professions go in such nature I guess. Evil is infectious, like virus. There are good lawyers/evil lawyers, whitehat/blackhat security researchers. Hell there are teachers too who train others to become “better” at killing. It all comes down to what your beliefs are and how you are influenced by them. Very few people can really answer a higher question like how is what they’re doing really impacting the world.
