Case Scenario: The teacher at the elementary school is in a dilemma after the school is locked down due to an active shooter in the area. While locked in his classroom alone, he can hear the shooter approaching the classroom. Across the hall, students are making noise, and the shooter is getting closer. He has two choices: either come out of hiding to distract the shooter and lead him in a different direction, knowing that he might die while saving the students' lives, or stay hidden, knowing that the students may die. This dilemma presents the teacher with two options; his choice will determine the fate of the students, their families, the shooter, and himself.
Based on the scenario above.
