Oh, and Canada geese are pure evil.
Canada geese are so evil there is special subgroup of evil just for them.
Praire dogs are good.
Candiru are evil.
So are yellowjacket wasps. I’m sure they just fly along thinking - “I’m going to sting something!”
Cats are nice. Death said so, and he sees the big picture.
Groundhogs are well documented to be both evil and nazis.
Butterflies are evil. They cause hurricanes.
“My Little Pony” is definitely evil.
Evil:
Black Widows - they pretty much flaunt how evil they are, by hanging upside-down in their webs, showing off their little red hourglasses. And when they walk, they do a little dance of evil.
Fire Ants - No number of mentions can possibly ascribe enough evil to these vile and awful creatures. One of the few creatures I’d be willing to say the world would be much better off without.
Any other ants - They have very little to recommend them, but they are a part of the food chain and all that and not quite as bad as their satanic fire bretheren mentioned above. Still, how can an animal that invades your house when it rains to get away from the water and invades it when it’s dry to find water be anything but a cruel and evil prank courtesy of satan himself?
Mosquitos - They suck blood AND spread parasites. Two evils for the price of one. Plus, the itching.
Venemous Snakes - Except the sea snake.
Mice - They gnaw, they stink, and they breed faster than rabbits. There is nothing good about mice unless you happen to be a snake.
Sea Monkeys - What a gyp.
Ticks - Ick. Double ick.
Fleas - See ticks, above, but with less burrowing into skin.
Chiggers - Give fire ants a run for their money. All the worst traits of mosquitos, plus volume, volume, volume!
Lampreys - Tied with hagfish for the Most Awfulest Fish award.
Octopi - They are the smartest invertibrates – “smart invertibrate” being two words you don’t ever want describing anything. They can open peanut butter jars and do other problem-solving things, and change colors, none of which are cute when done by an eight-tentacled bag of pus.
Good:
Pugs - No other dog is quite so Good as the pug, with the possible exception of the Boston Terrier and French Bulldog, both of which are practically honorary pugs, anyway.
Sea Snakes - They are super poisonous, yet not aggressive. That’s very zen.
Chinchillas - All the good qualities of rabbits, plus an entertainingly bizarre grooming method (they spin rapidly in volcanic ash, preferably in a small fishbowl.)
Echidnas - You have to feel sorry for them. They’re monotremes, but didn’t get a kid-friendly name like “platypus.” Instead, they sound like some kind of skin disorder. (“My echidna’s acting up again, Marge. Where’s the salve?”)
Cool:
Komodo Dragons - And monitors in general. Can’t qualify as “good” because of a number of traits, including bacteria-laden saliva so nasty it will kill you, and a preference for carrion and spoiled eggs. But they’re humongous, and look hysterical when they run or swim.
Sharks - Evil, but bitchin.
If by prairie dogs you mean gophers, then you would be incorrect. Gophers are evil. Ask any farmer.
I’m not sure, but I would hazard a guess that by prairie dogs, she meant prairie dogs.
That said, I would agree that gophers are, in fact, evil.
Okay, we have gophers here (or more properly, Richardson’s Ground Squirrels), not prairie dogs. Prairie dogs are cousins to gophers, apparently. It sounds like they are evil, too.
Dang it, hit submit too fast. Gophers (sorry, ground squirrels) and prairie dogs can carry bubonic plague - if that doesn’t move them into the “evil” category, I don’t know what does.
There’s an X-Men story I do NOT want to read!
the most evil creature of all is the dreaded Black Canyon Squirrels of Supai, AZ. I once personally saw a 4 foot tall canyon squirrel untie the rope which secured our food, lower the bags to the ground, and then complain that we didn’t have more M&Ms. Frankly, we were lucky to get out of there alive.
Bo
(eyes fill with tears) But they’re wonderful. I adore octopuseses. And don’t forget that they can run on two tentacles, also.
Woodchucks are indeed evil, but I’m happy to report that I’m a card-carrying member of the local Woodchuck Slayers association. I got one with my car, once 
Goldfish are good. Cows are good.
Yellow jackets are evil aggressive monsters who are also cannibals.
Hey - so are the ground squirrels! Evil, evil, evil.
Good: tantor, manu, the mangani in general with a few exceptions (i’m looking at you Kerchak and Terkoz).
Evil: bolgani, histah, numa, sabor, sheeta, gimla
Good to eat: bara, horta.
I’m not sure what the OP is exactly asking. I assumed it was more about the usual representation than about our own personnal feelings. For instance I like crows, but indeed, in the western tradition at least (contrarily to some amerindian, germanic, celtic,…myths) , they’re normally negatively connoted.
And cats quite often symbolize evil things, are associated with the devil, appear in horror movies, etc…
Over here, owls traditionnally announce death. They were crucified on the barns’ doors to repell evil or bad omens (I don’t know if it was an european tradition in general, or specifically a french one).
Jamie Lee Curtis often appears in horror movies, but you wouldn’t call her evil, would you?
Well, not to her face.
Actually, they weren’t evil per se, they were simply harbingers of evil. In the story, when the pigeons showed up, hilarity did NOT ensue.
PfH was made into one of the best episodes ever on the old THRILLER Tv show hosted by Boris Karloff.
Many Native Americans don’t love the Owl.
I think all insects are evil.
But what about me?
