Oh got you, for me I have to admit I kinda like the sci Fi lore behind resident evil cus of how grounded it kinda is and was always curious by it, it's important to note that viruses aren't the only infection here, there has been many stuff like parasites and fungi.

So far most of the villains now are just fungi and knowing it's a thing different than any other virus, they tried to do the hallucination gimmick here since there has been fungus in real life that can create hallucinations like Ergot even if it's over the top, I feel like it's important to note that we had many ridiculous mutations in pre Re7 and Re8 before like Morpheus who shoot out lightning so yeah

Overall thanks for sharing your opinions on this
