People do see how bad it is in the movie. What I’m saying is that people do not believe anything in their reality is comparable. When I say that people see it as fantasy, I mean that they see it as an imaginary world with nothing comparable in their own world.
It makes it more dangerous : the sting is attach to the venom bag, so the venom bag gets to empty itself whole if it stays. Evolution would have chosen the survival of the hive, not the survival of the bee.
One thing is weird though : you can extract the sting of a wasp with a pincer. The wasp will live through it. Why do the bee dies when it loses it’s sting and not the wasp?
