OKay so lets say you had theskills and charisma to do the kinds of things that Derren does... would you use them for the power of good (or at least harmless) as he does? or would you use them for your own gain?
I'll be honest and say I'm not sure... I mean if I could suggest on an unconscious level for my boss to give me a raise or to distrust a fellow employee that I hate... would i? yeah most likely!
would i also use it to help friends perhaps move past a mental roadblock they seem to have... yes as well... but i don't think i could resist the temptation to see what all you really could get away with.
