One the one hand, there is no reason he didn't take the Alpha spark from Derek.

On the other hand....Peter, in this past episode, was not heroic or selfless in helping them in Stiles'. He wants to know everything that Talia stole from his memory. He needs Lydia for that. He didn't shout "SCOTT!" when things seemed to going badly. He shouted "LYDIA!" because he needed her to survive.

And how do you think it would have gone for Lydia if he'd killed Scott while Scott's claws were in her brain stem? Cause I'm guessing that would have been bad -- not to mention the fact that Deaton and Mama McCall were *right* there and probably would have had some strong objections.
