What happened to the witches?

[kılıç_mehmet]

I never heard of a story where the success of one's neighbor was blamed on the devil.
Here, it's rather blamed on God.

Men and women in Salem believed that all the misfortunes were attributed to the work of the devil; when things like infant death, crop failures or friction among the congregation occurred, the supernatural was blamed. Because of the unusual size of the outbreak of witchcraft accusations, various aspects of the historical context of this episode have been considered as specific contributing factors.

It was particularly suspicious if your crops failed and your neighbors succeeded. The conclusion was they must be a witch rather than ergot fungi which is known to infect rye and is suspected to be the culprit of many of the Salem Witch Trials.

I see, but I'm not sure how you're going to blame your neighbor's good harvest on their accord of being a witch.
You can always blame someone else.
Here, you don't even need to blame them. They already tell people that they do sorcery, and people either go to them to bewitch their brides, mother-in laws, or break the spell on either of these.
That's how it goes for the most part. I don't know why they chose to burn witches, or those who they thought of being witches, but it's probable that harsh times bring always the worst out in people.
