i think that in the end when victor dies, it is supposed to be like he couldnt live with what he did. he made it his goal to find the monster, when i really think that he was searching for reasons why he did the things he did and when he died, the monster will die too. 

i think its really odd that the people who die are all killed by the monster yet victor was the last one to see them. i think that this is a possible hint that the monster doesnt really exist but it is just victor doing this stuff subconsciously. I think that when victor created the monster it was more of that he discovered the monster within himself 

i think that victors fear of the confrontation with the monster is really the fear of a confrontation with himself and the way he really feals

i think that the threat that the monster tells victor after victor destroys the female companion could really be victors fear that all the secret hatred for elizabeth(because she was the reason for his mothers death) will come out on their wedding night

im not so sure that everything that is happening is really happening. I kind of think that this all might be in victors head. i think that when he "wakes up in prison" it could be his imaginations way of punishing him for all his wrong

i think that victors fear about creating a female companion for his creature could be an issue with the genital stage. he is scared of what could come from this mating

i think that the monsters fear of rejection is just like a child's fear of abandonment by their parents
