I don't think you understand detachment. Detachment is detaching your feelings from your S so that no matter what you do or how they react, you aren't hurt emotionally. It's like seeing them as a friend and not as a S.
You need to detach regardless of what actions you do. It's not a 'tactic'.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
