The monster was not Frankenstein, the Doctor was. Doctor Frankenstein created Frankenstein's monster.
Frankenstein believes he has the right to take the life of his monster because he views the creature as a threat to humanity and a source of his own suffering. He feels responsible for the havoc the monster has caused and believes that eliminating it is the only way to protect himself and others from further harm. Additionally, Frankenstein grapples with feelings of guilt and regret for creating the creature, which fuels his desire to destroy it as a means of reclaiming control over his life and actions.
When Victor Frankenstein pumped electricity into the monster's body, the monster was brought to life.
The monster feels entitled to seek revenge on Frankenstein because he perceives his creator's abandonment and rejection as a profound betrayal. After being brought to life, he experiences intense loneliness and suffering due to society's hostility and Frankenstein's refusal to acknowledge him as a being deserving of compassion. This perceived injustice fuels the monster's anger and desire for vengeance against Frankenstein, whom he holds responsible for his misery. Ultimately, he seeks to make Frankenstein understand the consequences of his actions and the pain of being forsaken.
In Mary Shelly's novel Frankenstein, Dr. Victor Frankenstein discovered the secret of life itself when he assembled his monster and brought it to life.
Frankenstein is the name of a scientist who tried to create a person. He worked tirelessly to accomplish this feat. It backfired on him when he created a monster. Most people think that Frankenstein is the name of the monster, Frankenstein is the scientist's last name. Although many people have come to believe that the monster's name is Frankenstein, the monster's creator is Victor Frankenstein. Victor Frankenstein is the main character in the novel Frankenstein by Mary Shelly. Not the moster as is popular belief. Victor created the moster, who remains nameless. Shelley later stated that the monsters name was Adam. Frankenstein is a monster that was made up from the body parts and organs of the dead, by Dr. Frankenstein himself. When the monster was complete Dr. Frankenstein shouted "It's Alive! It's Alive!" when actually Frankenstein was never really alive, because if you look over the five characteristics of life Frankenstein dose not have all of them so he could never have actually been alive. Frankenstein is the last name of the scientist who created the monster. The monster is never given a name. It can be assumed that Frankenstein is a fitting name for the monster, since he is, in a way, Victor's offspring, therefore should share his last name. However, nowhere in the novel does the monster get referred to as "Frankenstein." Also, the "it's alive" bit is true only of the movie. In the book, Victor runs away in fear when the monster comes to life.
Victor Frankenstein is the scientist, who studies chemistry and is obsessed with the creation of life. Frankenstien later constructs a creature out of body parts and brings it to life. Victor Frankenstein did not name his creatre, it is often known as Frankenstein's Monster or Frankenstein's Creation. Frankenstein calls his creation the "daemon".
Victor Frankenstein's life story is at the heart of Frankenstein. He learns about modern science & masters all that his professors have to teach him. He becomes fascinated with the "secret of life," discovers it, and brings a hideous monster to life.
In Shelley's original work, Frankenstein's monster was created by means of Alchemy that are not detailed in the book. In popular media, though, Frankenstein's creature is often brought to life by being stitched together out of various organic parts and brought to life by lightning.
