The senior prosecutor for the Crown Prosecution Service (CPS) Wales said Carl Mills was responsible for "starting a devastating fire" that had "distressing and tragic consequences".
He did so knowing full well who was in the house at the time and the evidence of his jealous and controlling nature makes it all too clear what his intentions were.
Once the fire had taken hold, neighbours and friends of Kim, Kayleigh and Kimberley Buckley did whatever they could to try and assist at the scene.
In contrast, Mills himself displayed a callous, almost casual disregard for the well-being of those trapped inside the house.
