[b][i][u]SPOILER ALERT[/u][/i][/b]
[spoiler]Snoke says he isn't aligned with the dark side which would debunk the Palpatine theory, that would be a cool twist though[/spoiler]
When'd he say that? Ive heard rumors he is willing to use both sides of the force but Palpatine did that as well.
And considering he says he will complete kylo's training this would be dark side training. Not that kylo has killed his father the pull of the light side may be gone completely and i suspect this is what snoke needed before he was willing to train him further in dark side forces.
