Peter's Quote: "Its that spark of power that makes you an alpha. When you take her pain, she draws on the power that provides you with those special gifts, the power that heightens your senses, the strength, the power that transforms your body. As an alpha, you have that bit of extra... that spark. That intensifies the color of your eyes from a bright yellow into a searing red."

Deucalion's Quote: "Feel that Theo? That's the secret to taking power, pain. Take their pain, take their life, take their power. Its all or nothing. You take until there's nothing more to give, that's where you find the spark of power and then you take that as well. Pain, life, power, in that order and only that order"

As you can see there's a big difference between taking pain and stealing power. Taking pain is only the first step to stealing power. The writers haven't broken any established mythology.
