Just because the GR didn't take the party guests, doesn't mean they won't be back for them. Scott and Liam already came to the conclusion that the party guests would be the next targets. Once the GR pick their targets, they might not be able to go after somebody else until that person is erased. Corey and Liam tried to stop them but they just pushed the pair aside instead of erasing him.

I believe the GR want to wipe out everyone in BH, but only have the power to take one or two at a time. Aside from Stiles, the other erased people have been families (Alex and his parents and Phoebe and almost Gwenn).

They didn't take Stiles' dad, however, they did bring back his deceased wife instead. We have no idea why they did it, but they might have wanted to use Sheriff for something else, as we haven't seen other people's dead relatives come back. They left Sheriff for a reason and I hope we find out why soon.
