Frankenstein's creation is dangerous. He shouldn't live because of what has happened to him throughout the movie. Others may believe that he should be killed because he doesn't know better and he is able to be retaught. But because of the things he has done, it is most likely going to be too late for his to be retaught. Here are reasons why he should be destroyed as in killed.
From the beginning of his existence the creation wasn't taught correctly meaning he was abused by Fritz, the assistant. He would get whipped or totured by having fire in his face. When Fritz did that it taught him to use violence against others when they would touch him or have fire in their hands. Frankenstein and Fritz didn't look out for the creation that much. He was always stuck in a room when he should of been adapting to the world outside the room and slowly getting to know people and words. They didn't teach him words mich besides "stay back" or "sit down". With them teach him violence he just wasn't wired right in the first place.
A big thing about the creation is that he is abnormal. He doesn't have a normal brain, he has a criminal brain that was stolen for a university that Frankenstien use to work at. His brain works as criminal which means he may have impulses that can cause him to do horrible things like hanging Fritz. He can go out and hurt someone. It all depends on the person's brain he has but would you take that chance to find out if he is capable of that or not?
Maybe the creation can live in peace with humanity. He could probably be retaught the correct things to do and go to places.
