Villian role:
The villian in the story is Jack because he shouldn't be going or entering into someone elses property & stealing something. If he needed money, he should have just worked for it instead of stealing something then selling it. Instead of selling the cow, he could have killed the cow...and that would have been their meal for about a few weeks. In the first place, Jack should have thought & never took the magic beans.

Good Guy:
I believe that no one in the story was the good guy because no one did anything good. Jack stole many things from the giant. The giant would have killed Jack if he would have found Jack. The bean seller sold magic beans to a kid and the mother didn't return what Jack had stolen, back to the Giant. So thats why i believe that their was no good guy in Jack and the Beanstalk.
