Such things are noted. Tech supposes the reasons make as much sense as anything. He's not particularly used to assigning feelings to any given thing but in this instance he can say it is a sad thing.

"...and that's just how they must be? Without appease?" It sounds like a miserable existence.

Tech matches Vader's pace, looking around at the headstones and markers as they begin to pass a few, watching where he treads. The Sith lord gains his attention again then. "Why would you want to bind one? ...are they not already technically bound if they linger?" And resurrection..? His brows lift at that.
