sonny chiba’s voice over in the beginning of the movie elaborates on this theme as well i think…it’s the central theme of this particular (and many other) revenge story. revenge can be exacted more efficiently, effectively, and brutally when pursued in a cold, detached, and unemotional way.
the fact that it’s a reference to star trek also serves to remind us that this is a MOVIE movie (as someone else already stated) taking place in an alternate universe, plus it’s a cool pop culture reference—which we all know is QTs specialty…
