It might be necessary. Note Ultra Magnus' words to Prowl: "You believe the information would tear the Autobots apart...". Prowl might be dead wrong. The dead Autobots died for Prowl's assumption, not a proven scenario.
At the very least, it is a "better safe than otherwise" scenario. The potential damange the information could have done justifies the effort made to keep it quiet.
A word of respect for the dead would arguably have been just as trite as "life persists".
don't see why 'happy ending' and 'intelligent writing' are mutually exclusive. But no, I'm not arguing for a happy ending, just one that offers an actual reward or laudable goal for the pain and suffering. Make the prize that was obtained worthy of the cost. And it simply wasn't.
I am not saying that happy endings and intelligent writing are mutually exclusive. I have read plenty of stories with grim endings, (because they wuz hard-core you see), that were hardly what I would call intelligent. After a while, it got easy to spot the "oh no" element that would ruin things for the hero. A "suprise" grim ending is just as predictable as, and no more intelligent than, a standard happy ending.
But, in this case, Roche gave us an intelligently written story that would have been undermined by a happy ending. The good guys are a team of no-so-nice guys who are kept on pay-roll specifically to deal with the very worst situations, such as a prison break orchestrated by a mad man pitching a tantrum.
Stopping Overlord and reclaiming the politically explosive files is a more than laudable goal in story. Roche's writing on the subject makes the meta-cost worth it.
You've got a bizarre definition of "more cheerful".
I was thinking in the, "If you think the ending as it was is bad, how would Magnus and co shooting prisoners in the head grab you?", sense.
When Impactor does it, it's a horrible thing because we expect Autobots to exercise a higher level of morality. Something that Impactor himself realizes when he doesn't kill the helpless Overlord, despite the fact that Overlord deserves death a thousand times over.
Wasn't there also a line about being a more or less crippled prisoner being worse for Overlord?
Either way, I think Impactor's biggest crime was less shooting the prisoners than how he did it.
He did so in a way that could have implicated his troops. He killed them in a way that could have dragged another planet into the war, (despite that planet really just wanting to stay out of it).
Had he taken the Decepticons off planet and then killed them, that would have been more defensible. He could have taken them off planet, and legalistically "released" them after mostly disarming them, (he would need to leave them just armed enough to attack him and justify his killing them all in a legal retaliation).
Or, he simply could have shot them, buried the bodies and lied to his commander about letting them go.

-not sure letting them go would have been an excercise in high morality.
