If, more specifically, you're asking if the taking of an innocent life would effect Alpha eye color - we don't know since no "innocents" have been killed by an Alpha on screen to date. Peter killed his nurse but she wasn't innocent since she helped him kill Laura and the rest.

Also please clarify for me, did Peter Kill his nurse? I know he stuck her in his trunk and made it sound like he killed her by saying "I got better" when Stiles saw her body, but it looked to me like Derek killed her when he knocked her unconcious and left her bloody body on the floor of the Hospital in "Wolf's Bane." Did they ever end up actually saying Peter killed her after that?
