There are many theories as to what the reaction of the public would be if Victor’s creature was ever shown to the public and the most common one is found in a great majority if not all movie adaptations.
For example the 2015 movie “Victor Frankenstein” has Victor and Igor create the creature and then animate it in front of a small audience. this leads to many of them being revolted, a few being interested, and the police trying to destroy the monster they have created. Ultimately the two main characters destroy the creature themselves.
Basically the creature being introduced to the populace would always spell disaster according to the adaptations and general logic. Most people would see it as not something that should even be attempted and as an abomination that needs to be destroyed right away.
