Kylo had never been prepared for the role he currently finds himself in. Even in the moment he chose it. Killing Snoke hadn't been a plan. It had been a moment of opportunity born out of desperation, and one that had ultimately not played out remotely like he had hoped.

Every doubt he's had about any of it is something he's had to carefully hide so as never to reveal it to anyone but himself. Letting it be so open now is more than strange, but it seems he had been right all this time to allow his grandfather's silent spirit to serve as his one confidant. There's no judgement in Vader's answer, for all that Kylo can't completely shake the imagined criticisms that Snoke would have given in his place.

He simply nods in reply, choosing for now to let all those answers sink in rather than trying to find words to say in return.
