Maybe it helps to understand that there weren't all that many colonists in Massachusetts at the time. It was a harsh environment and survival was always precarious. So a place like Salem village relied on Salem Town and both relied on Boston for support. The witch trials weren't a matter of backwood ignorance but educated elites stepping into a bad situation and making it worse. To give them credit, they (or their superiors) were also the ones who eventually halted the hysteria. But it was too late for the ones who suffered.
There's a great old book you might like, Danik, called The Devil in Massachusetts by Marion Starkey. It's a popular history and old so the scholarship is not going to be cutting edge, but it is accurate in its narrative and really fun to read. I just found a reprinted ebook on Amazon (for the low, low price of $3.99). There are some more current books listed there, too, but I've never read them.
For almost all adults it was just an out of control situation and a horror. The only ones who benefitted were the family members of some of the girls. After the girls power grew, several of them began to accuse family enemies or people whose land their families wanted. But there is no evidence that their families were actually behind this, whatever they may have thought privately. If they had anything to do with it, they never confessed.
