Direct Answer

Why It Matters
The killing matters because it exposes the weakness in Jacob's distant leadership. Ben served the Island, led the Others, and sacrificed his daughter emotionally and politically, yet Jacob never gave him the approval he wanted. That wound becomes the opening the Man in Black exploits.
Story Context
The Man in Black wears Locke's body because Locke's death and faith give him authority over Ben. By the time Ben stands in front of Jacob, his question is personal: what about me? Jacob's answer, 'What about you?', detonates Ben's deepest insecurity.
