Nah people with the "hacker inclination" are just as easy to buy but in other ways. There are people who will solve any interesting problem put in front of them and have a great time doing it without reflecting on why someone put it there or what it will be used for when they're done. Giving them more interesting problems, more autonomy to pursue intellectually stimulating solutions to them, is the reward you can use to keep them building your drone assassination algorithms or whatever.
In fact the overwhelming consensus on this site has long been that skillfully solving problems that are personally interesting to you is at worst morally neutral. I'll bet significant number of the people who work at for example palantir are like this. Curiosity-driven "little eichmanns."
