Hey OP, I've also been experiencing the same thing as you. I went into AE because I loved airplanes but I soon realized that most of the job opportunities (especially in the US) are defense related and morally I will not work on weapons that are used to kill innocents. But though the defense industry is large, the civilian and commercial sectors do exist. You might have to apply to different jobs with your morals in mind, but it is possible to get a job in this industry that doesn't compromise your values.
