Headscratchers / Mortal Kombat: Annihilation

• Kahn kills Rain for not making his enemies beg for mercy before dispatching them. Why he would kill a general whose troops just offed two of Earth's best warriors for that reason is baffling. The closest you get is Rain quickly saying "But master, I thought if I let them live-" before being cut off, but that could mean anything.
  • It could also be interpreted as an echo of the earlier scene where Shinnok asked Kahn if he'd made Raiden beg for mercy before killing him; Kahn, knowing that neither happened, was hesitant to admit that failure to Shinnok. In the same way, Rain merely said that Kabal and Stryker were "taken," meaning possibly that they were captured, not killed; Kahn's expectation was that they should have been killed, and when Rain admits that this wasn't the case, he was killed for showing mercy.

• Why are the heroes taking Kahn's seven-day deadline at face value? Wouldn't that have been a shock to them if Kahn showed up on Day 4 instead?
  • Fridge Horror to add to this: Everyone, including Kahn himself, was saying that the seven-day deadline was necessary for the realms to completely merge and for Outworld to be totally victorious; however, Kahn could just as easily have struck on any day prior to Day 6, especially since there's not much indication that that much time has passed between Kahn's initial appearance and the heroes' arrival in Outworld (the most we see is the change from day to night to day from Kahn's first arrival to when Sonya finds Jax, but that would mean only two days have passed, and we don't know how much time has passed since the latter point)—he just did it this way to screw with Raiden, who it's established loses more of his powers the longer the merger goes on.

• Why didn't Raiden kill Kahn's army after Johnny Cage is killed? He seemed as if he had the power to do so when preparing to exchange himself to Kahn.
  • For that matter, why didn't Raiden just kill Kahn himself during their initial fight? He was wiping the floor with Kahn after the initial surprise strike-down Kahn gave him, and only started sharing the Idiot Ball with Sonya when Kahn roped her legs and dragged her into Distressed Damsel mode.
    • As we learn, Kahn is his brother......so obviously not kill him. He may not have also wanted escalate the situation without first speaking with the Elders. Then again it did seem like Raiden could have done whatever he wanted.

• About "The Earth was created in 6 days" sentence... which was said at the beginning of the film by an Outworlder. And not by just any Outworlder: Shao Kahn himself is the one who says it. There is no way that he could read the Bible in his spare time... Is he a Wicked Cultured, or what?
  • Or the Earth was literally created in six days, perhaps all the realms were.
