The Sentry Angel killing you isn't an event in the list. The event that you will receive in your Event List is the third "Consciousness Simulation End" scene. It's the fourth event total, and it has two down arrows next to its name.
There are three separate versions of this event, all determined by separate actions:
1. Complete the Consciousness Simulation by shooting the Absolute God 2. Die during the Consciousness Simulation 3. Get killed by the Sentry Angel before the Consciousness Simulation
