One can make any number of horror-movie monsters by removing the limits from some natural desire or process: Alien is reproduction without regard for anything else; The Blob is pure and unlimited growth (with unlimited consumption as a corollary); The Thing is a sacculina-esque parasite that places no limits on its own desire to survive etc.. There are two sides to removing a limit: on the one hand we get a monster and on the other hand we get godlike power. These two aspects can be reflected in the plot when protagonists want to kill the unlimited thing as a monster and antagonists (government officials) marvels and desire the unlimited thing as a god. The marvel of the antagonists is tempered by the fact that they do not simply marvel at the godlike thing but also desire to possess and control it. Such possession itself is a claim to unlimited power, and so is a redoubling of the monster.

You’re about to go all Feser on us? š
Most of the fun stuff in vampire story-telling comes from the consequences of removing death as a limitation and the deformities that follow. Infinite life as a bad thing?

Part II was about how this was an insight into matter. The limits the Vampires transgress aren’t the ones on life, but on diet. Diet and maidenhood.
Totally missed Feser on Vampires.

There is also the interesting fact that many horror movies (Friday 13, Psycho) begin with a sexual transgression (a removing of limits) that ends up releasing the horror.
