If I have Lady Matsu's Rage out and I target a berzerker with a kill action and my opponent delays it with Halls of the Forgotten, will Lady Matsu's Rage trait be triggered?
I'm thinking not because the action will resolve and the berserker will not have been destroyed at the time of the action's resolution.
Even after the battle ends and the berserker dies, I don't think the trait will trigger then either, correct?

Until Embers of War is released, this thread about Halls of the Forgotten and Feign Death may be useful.
