Making stone soup helped the villagers by bringing them together. They were suspicous because they been through famine, floods, and war. 
In the story it says that the villagers were hard working but didn`t trust no one but themselves becaues they have been through famine, floods, and war.  In the story, it also says that at the end of the story they wasn`t fighting anymore they had freedom.
One last thing in the story it says the villagers got along by giving and trusting one another.
This shows that the villagers change their ways by sharing, caring, and trusting. This also shows that the villagers have trust for one another.
This reminds me of a time when I was hating my brother when he beat me up and he ask for forgiviness and I said yes and I trusted him again just like the villagers trusted one another.
