My brother in law is using his engineering degree to work for various arms companies, including DARPA. His wife justifies it by saying “He only makes things for good countries like the US”.

A few years ago, he, his wife, my wife, another sister in law and his kids were in a car, and he was talking about why it’s justifiable to drone-strike school buses. He said “Well, there were some really bad people on those buses.” I ask “What makes them bad?”, and he says “You know, they make bombs, that sort of thing.”

I turned to him and said “YOU make bombs. By your rationale, this car with your entire family is every bit as much a justifiable target as those school buses.”

The entire car went silent, and later, my wife thanked me for not going any further.

He’s the most morally-bankrupt person I’ve ever met, and I hate being in the same room as him. His wife isn’t much better, and is the epitome of the portion of the working class that’s been tricked into thinking they’re better than that. She’ll handwave away the fact that in her career, she’s been directly responsible for firing thousands of people “for the good of the company”.
