It sort of goes with the flow. I mean, transporter operators are always doing this sort of stuff. "Kirk to Enterprise: three to beam up!" never incites conversations on subjects like "Uh, which three out of that crowd would you happen to mean, exactly, Sir?" or "What happened to the other two landing party members, Sir?". Quick reflexes are called for in most scenarios; thinking is optional.
Klingons have been well served in that respect IMHO. Some yield gracefully to Kirk's besting them (Kor, Koloth); others die cowardly or grisly deaths for their villainy (Kras); some choose to cooperate and come off all the more victorious for that (Kang). Kruge just happens to be the despicable sort of villain deserving of the middle fate.
I'm more concerned with the henchmen. Kirk spares Maltz' life, but callously guns down the goon guarding the encampent, with the rarely used "kick across the set" setting. What happened to waging war on stun ("Errand of Mercy")?
Then again, wasn't it that very goon who killed Kirk's son? Not that dad would know.
