That is exactly how I play my Inqui 
you don't.
you have the options to make decisions into the game...
your inquisitor can be whatever you like to be .... as example 'naive, stubborn, inpatient, inflexible women with no political knowledge or skill in charge of the Inquisition'
but the decision options you can choose into the game ar not naive, stubborn, inpatient, inflexible... no matter which decision you make it looks like that you are a true leader .
you haven't the choose to be naiv or stubborn if you must decide something.
into the situation where you have to make decisions they effect the inquisition ... all your options will be wisley.. strategy .. policy ..tactical correct.
maybe because of the work of your efficient advisor cullen , lelianna and jospehine.
maybe you are the official leader of the inquisiton but without your advisor you can't do it.they help you with the leadership.
the general kinky behave of your inquisitior doesn't matter at this point....i think if you wanna play as a person with a kinky behave then you should see your advisor more as teacher.. because they show you how to lead.
anyways you can be crazy like hell but if you have the decision about life and death of other ones...then would also a kinky or silly hero put his own behave aside and start to think serious about all that.a hero would use his human understanding to be able to lead.
and no matter if you lead the inquisition or not....the game is all about that you be the hero.. and heros have always obligations.
