He is responsible for all the deaths and destruction caused by his creature. The creature cannot be responsible for the devastation it causes, because it is simply a mutated experiment that has not been properly contained. Victor was the provider of this experiment, but he never took responsibility during the entire journey. Victor's obsession with being the one who brings death to life blinds him to the consequences his creation could bring throughout the entire story. Victor Frankenstein is the brilliant mastermind behind all the death and destruction. The “Merriam Webster Dictionary” defines a monster as 'a powerful person or thing that cannot be controlled and that causes much trouble'. Victor Frankenstein is the epitome of the word monster. He was in charge of the experiment which gave him a sense of power. Even though Victor himself was aware that he was harming himself by obsessing over the experiment, he couldn't control himself to stop what he was doing. The uncontrollable impulses that Victor portrays prove that he is the true monster of the story, and the creature is simply a reflection of Victor's true identity.
