With Heimdall to pave the way, Luke no longer needed to waste time personally persuading the Asgardians.
As the gatekeeper of Asgard, Heimdall had a very high standing and a good reputation here.
As long as he said a few words, the remaining soldiers and civilians would basically follow him.
Although Hela didn't massacre civilians, she didn't try to win people over like in a regular political grab for power.
She simply told her skeleton soldiers to kill the rebels.
In the last few days, a lot of civilians had been detained for interrogation. If they said they didn't know anything, Hela made an example of them in public.
She announced that the interrogations would continue as long as the Bifrost sword couldn't be found.
Such a high-handed method made the civilians of Asgard panic.
Previously, they had nowhere to go. Now that Heimdall said that he would send them to a safe place to hide, most people chose to leave.
