As for season 1, he probably only cared enough to figure out Stiles, Allison and Melissa were important to Scott. They were the only ones that kept him "human."

Allison was his anchor, Stiles was helping him learn to control his shift and is his BFF, and Melissa, being his mother, is obviously important to him. Beyond that, he just wanted Scott to either kill and be part of his pack, or die at his (Peter's) hands... er claws, whatever.
