* Guilt and remorse: Victor is deeply tormented by the monster he created and the suffering it has caused. He feels responsible for the monster's loneliness and the destructive path it has chosen. Creating a companion is a way to alleviate his guilt and attempt to offer the monster some solace.
* Hope for redemption: Victor believes that a companion might help the monster find peace and integration into society. He hopes that by creating a creature similar to the monster, they can find solace in each other and perhaps learn to coexist. This is a way for Victor to redeem himself and perhaps prevent further tragedy.
* Fear of the monster's destructive potential: Victor fears that the monster's loneliness and anger might drive it to further acts of violence. He hopes that a companion might distract the monster and channel its energy in a more positive direction.
* Desire to control the monster: Victor may also be driven by a desire to maintain some control over the monster. By creating a companion, he believes he can influence the monster's behavior and prevent it from causing further harm. This ultimately backfires, as he ultimately destroys the female creature and the monster's rage grows even more intense.
However, Victor's decision ultimately leads to more tragedy. He fears the potential for the two creatures to reproduce and create a race of monsters. This fear leads him to destroy the female companion, leaving the monster even more isolated and vengeful. Victor's attempt at redemption ultimately fails, and he becomes trapped in a cycle of guilt and despair.
