Who was responsible for the murders in Frankenstein?

 “Is Victor ultimately responsible for the murders in the novel or is he a victim?” is the essay’s prompt and you need to have text evidence from the actual book, plus some secondary sources to back it up.  Do the secondary sources, the writing and works cited for the secondary sources. Frankenstein quote list you could use: ‘This passion is detrimental to me, for you do not reflect that you are the cause of its excess.’ (The monster/creature to Victor Frankenstein explaining how Victor is the one responsible) ‘The tortures of the accused did not equal mine’ (Victor Frankenstein feels guilty that other people are being accused of a murder that he feels responsible for) “As [he] heard it, the whole truth rushed into [his] mind, [his] arms dropped, the motion of every muscle and fiber was suspended; [he] could feel the blood trickling in his veins and tingling in the extremities of [his] limbs.” (This is just a realization moment)
