The thing about Merril is that in the entirety of the game, when it comes to Mages that don't turn into Abominations... it's her and Alain.
Maybe they know something you don't.
actually there are a few more you meet along the way that dont turn into them either. i can think of terri(starkhaven mage you can rescue who then sends you letters) and bethany for another.
merril isnt insane really. she has very strong convictions about regaining the elvhen lost history, culture and etc. she believes that to be able to restore anything her people have lost is worth almost any price, including the possibility that it ends up claiming her life. she didnt just one day decide oh i should really restore the mirror that took my friend, but no one will help me so let me summon a demon willy nilly to learn blood magic with no preperation beforehand.
She spent her whole time as a keepers first studying alot of magic theory and practice along with what ancient secrets of such the clans keeper have saved. she was careful as she knew she needed to be when learning blood magic and dealing with demons. so she didnt just go hey demon come over here and teach me magic, teehee
She believes so strongly in this that she leaves her clan and everything she knew and comes with you to kirkwall. you think she is going to pay attention to anders the mentally unhinged abomination, or fenris 'i hate all mages because some mages made me a lyrium infused death stalker slave'? the only person i could even see her possibly listening to is hawke but i doubt that too, it would seem like the one person she could count on has betrayed her core of what she believes.
and as for her acting ditzy and naive about things in kirkwall, its due to the fact that she rarely interacted with the people in her own clan and has never been in a crowded city before. this leads her to be socially awkward, inquisitive about everything, which comes off as very naive, ditzy, on the verge of stupid. consider a person raised in a secluded farm or country area for most of their life, going into a really big crowded city for the first time. either they freak and get scared and nervous, or they stand amazed and in awe of all the things theyve never seen before(including a mugging). merril is the latter of those 2 for the most part.
so there you go, i believe that is a fairly accurate analysis of merril's character, beliefs, motivation, background and how it correlates into how she acts in the game. hope this helps!
