Ren was turned to the dark side by Snoke. It's even explicitly stated in TFA he's responsible for Kylo's turn. And even though Kylo had more screen time, he was essentially just the instrument Snoke used to hunt down Luke.

Also, where is it stated that Starkiller Base was under construction prior to Snoke becoming Supreme Leader?
