Yes, monster myths have always held the function of moral lessons for the many cultures that birthed them. The Wendigo is a moral metaphor for the taboo against eating human flesh, and the necessity of working together through harsh winters, as opposed to greedy wendigo, that works only to sate itself, and thus is cursed never to be sated. The Vampire is a moral warning against demanding excess in all things carnal, monetary, and gluttonous, and for this reason it resonated with Victorian england. The zombie, however, was originally just someone who had been drugged into submission. The modern zombie does, however, make an excellent metaphor for herd mentality and “us-vs-them”. We change our monsters (or make new ones) to fit the social mores and taboos of the culture of the time. There is a reason that many examples of “The Monster” in literature focus not on the actual villainy of the Monster, but on the villainy of the other humans in the story. Monsters are a mirror, held up to the face of the reader, demanding that we stare at the worst parts of what it is to be human.

I’d rather live as long as possible, the idea doesn’t seem to bother me oddly enough. I’ve thought it through and still think I’d prefer extended life lifespan. I could elaborate, but people don’t generally like hearing my views on such things so I’m not going to.

That said, I think your opinion is the most common that I’ve heard, and it’s understandable.
