maybe the whole inquisitor getting angry thing because they become spoiled with all political and military power and secrets in thedas that they hold? like. yeah sure, i saved orlais, be grateful. i gave a chance for the wardens to rebuild, be grateful. king alistair/queen anora is one of the first supporter of the inquisition, very nice. i discovered who killed the divine, be fucking grateful. or maybe it's more of a... personal feelings. like, they're a sole survivor, they were granted this mark that they never wanted, they join the inquisition solely so the chantry won't go after their head, they're unwillingly forced to become a leader of organization oriented to the chantry (this might be worse if the inquisitor is non-human). they work tirelessly to secure power, to bring stability in the middle of chantry chaos, orlesian civil war, and mage-templar war. they're forced to deal with political bullshit despite living in secluded place/wilderness their entire life. heck, the inquisition could also accidentally kill the lavellan clan. lavellan is also faced with crisis of faith, because they found out that their gods are not what they seemed to be. they unite thedas with any methods they have and... well. people are angry. mother giselle once mentioned that the inquisition puts down their sword after they finish their job. what if... they hadn't.
