No one can say you can handle or not your power without causing disaster zathrian was powerful mage and yet he created disaster same for magisters that went to black city everyone have flaw but in mages case price for that flaw is enormous.
Do I have flaws, of course. Could the flaws I have lead to doing some enormous tragedy, no. Sorry, but I know myself too well. Zathrian's hatred is what lead him to do what he did. We don't know what sort of people the magisters were. With great power comes great responsibility, if you can handle that then why would I be an issue for your assualt? I dont expect to change your mind or mindset on whatever problem you have with mages or devotion you have with the Templar order. I'm simply saying if I was myself a mage in Thedas I would have no need to be your enemy. I'm a very strong willed and independent person, but I have a right to defend myself against anyone who would do be harm for no reason other than being born what I am be it from close minded citizens, templars, or demons.
