Another interesting question to ask is whether the heroes really had a duty to help the Rigel colony.
It might be strategically wise to feed Rigel to the DDM so that Starfleet could get the time to work out some sort of a response. This would be callous in any case, and would probably be illegal if the Rigel colony were a UFP system our heroes had sworn to protect. But there's no indication that the Rigel colony would be a Fed location; the L systems appear to be distant from the UFP, which doesn't work if they are proximal to a major Federation colony of millions (as opposed to a random outlying settlement of a hundred luddite isolationists or grumpy miners or whatnot).
Do our heroes have the duty to protect random foreign life? Even if doing so means going against the interests of other random foreign life? In this case, things are simplified because stopping the DDM doesn't require directly killing any life as they know it, Jim. But one can't realistically expect Kirk to be tasked with gunning down Death wherever He appears. People die, planets die, civilizations die. Sometimes there's a Starfleet starship there to witness it happen, but usually there isn't.
Enter "Paradise Syndrome" where our heroes make exceptional effort to save a random planet from an asteroid, even though the next one will probably catch them anyway, and "they" are a tiny bunch of transplants in the first place. Is this what Starfleet requires of our heroes? Or does Spock go beyond the call of duty in crippling his ship, and would Starfleet have been satisfied with Spock flying back to the planet, searching for Kirk (and perhaps finding and rescuing him), and then leaving the planet to be destroyed? (Would it have been destroyed? Or would the Obelisk have protected it, quite regardless of whether there was a trained Medicine Man there, and the only reason it didn't was because Kirk had pressed some sort of a snooze button - or even because it was in any case only going to do the deflecting at the very last minute?)
Many if not most of the planets in jeopardy in TOS are either unidentified in their affiliation, or established not to be Federation worlds. Kirk helps them nevertheless - but almost invariably only because the threat of the week makes the mistake of also threatening Kirk or his crew directly. Kirk's first duty might still be for the Federation, and that might very well call for feeding the Rigel colonists to the interstellar wolves.
