That's not what makes Dahmer evil! He murdered and tortured (and cannibalised) other people!
Are we genuinely arguing if Jeffery Dahmer would be considered evil in DnD?
I mean come on.
He's evil by our standards.
What I'm talking about is a completely different species treating us the same way that we treat others species.
They don't torture us to much except in the act of the hunt might not be the most painless. P
What if the hivemind doesn't speak and communicates telepathically? And they can't communicate with us as they can't talk? Our speech to them is the equivalent of bleating from a sheep to them. Sheep bleating doesn't save them from the dinner table.
Thri Kreen on Athas ate sentients and weren't regarded as evil because of it. They liked elves.
To them we're just self propelled monkey bacon parasites as let's face it we don't serve any ecological niche.
And they treat us the same way we treat animals. Hell they might be Druids and think that in addition to food they need to cull our numbers.
Our cities could even be nature reserves. Once they get to a certain size nom nom nom.
If they have ancestral memory/semi immortal they would remember us being hunter gatherers and could compare that to the ecological impact we had once we settled down.
Even as hunter gatherers we wiped out a few species. As I said treat us the same as we treat animals irl.
