This study explores the roots of the devastation and bewilderment of those who witness the death of another person, and through these reflections, suggests that the responsibility of the survivor can be part of an ethics of otherness. Furthermore, by reflecting on these experiences that survivors naturally have, we will explore whether it is possible to educate students about the ethics of responsibility toward others. In the current situation where students are witnessing repeated mass casualty, moral education needs to lead these experiences into thinking about relationships and responsibilities with others, and through thinking about the ethics of otherness, it needs to address the discussion of the fundamental meaning of responsibility. This study aims to explore such a moral education discussion centering on Levinas's ethics of the other.
