Quote from : Why Does He Do That?: Inside the Minds of Angry and Controlling Men Book

The central attitudes driving the Drill Sergeant are: I need to control your every move or you will do it wrong. I know the exact way that everything should be done. You shouldn’t have anyone else — or any thing else — in your life besides me. I am going to watch you like a hawk to keep you from developing strength or independence. I love you more than anyone in the world, but you disgust me. (!!)
