I fear intelligence agencies more than standing armies, that our founders warned us about, because of their ability to direct and indirectly control armies, police forces, and the body politic.
CS Lewis made a similar observation —
On the one hand, a person with no moral compass who is “out for himself” can do a lot of damage, but may occasionally hold himself back (a little) and ask “Am I going too far this time?”
But someone with “good intentions”? They are convinced that the ends justify the means. They never hold back. They never question their own actions. They go full speed ahead all the time and they can do unlimited damage.
