"I suppose you have a point," he says, eyes still on the arm. "There are memories of mine that need to stay in the past, things I don't want others seeing."

Those memories involve bringing the temple down around himself, killing the other padawans, torturing members of the Resistance... You know, things that he has no problem with that others may have a problem with. He could see those things potentially getting him into trouble here. He'd own up to every bit of it, having no remorse for anything he's done, but it'd obviously be easiest to just not address any of his life before passing into the afterlife.

"Your arm..." He hesitates, finally looking back up to meet the soldier's eyes. "How is it a weapon?"

He doesn't have to answer, Kylo knows this but asks anyway. He's genuinely interested in what other galaxies can offer, especially knowing a great deal about the cybernetics his own has.
