Not a vegan, but I don't see how such a nonsensical game could possibly be thought to normalize harm to animals.
That's like donkey Kong promoting harm to gorillas, or Mario bros harm towards turtles.
Unless something in the brain isn't wired properly, these obviously cartoonish and completely removed from reality games shouldn't elicit a desire to harm anything.
Now, something like the 'realistic' scenes in Caddyshack, that's something else.
