Perhaps it's not the right term in English (sorry, my English is really poor), for detached I do not mean "not feeling emotions" or "not caring" but feel the emotion remaining rational, cold enough to keep ratio drive decision not emotions. I do not know a specific English term for that... If you "have powers" you can't simply act for yourself you have to take any other under your power/your responsibilities into account and act for the best for all. Since that's normally/often hard/impossible you need to being able to take hard choices, certainly not emotion-less (if so you are really dangerous) but also certainly not driven by your emotions. A balance is needed, like in any "engineering project".
