<![CDATA[ABSTRACT Guilt is a negative emotion that arises when individuals feel they have committed moral, social, or ethical wrongdoing. In students, excessive Guilt can affect emotional conditions, behavior, and the learning process at school. This study aimed to identify the forms of Guilt experienced by eleventh-grade students at St. Antonius Bangun Mulia Senior High School Medan and to examine the strategies used by Catholic Religious Education teachers in overcoming students’ Guilt. This study employed a qualitative approach with a descriptive research design. The research subjects consisted of Catholic Religious Education teachers, the principal, and eleventh-grade students. Data were collected through observation, in-depth interviews, and documentation. Data analysis used the Miles and Huberman model, including data reduction, data presentation, and conclusion drawing, while data validity was tested through source triangulation and technique triangulation. The results showed that students’ Guilt appeared in cognitive, affective, and behavioral aspects. In the cognitive aspect, students demonstrated awareness of mistakes and personal responsibility. In the affective aspect, students experienced feelings of anxiety, shame, fear, sadness, and regret that affected their emotional condition and learning concentration. In the behavioral aspect, students showed the desire to apologize, correct mistakes, withdraw from the social environment, and display perfectionistic behavior. The study also found that Catholic Religious Education teachers play important roles as educators of faith and morality, spiritual mentors, role models of Christian life, facilitators of religious activities, and builders of faith communities through warm, reflective, and non-judgmental approaches that help students understand mistakes as part of the learning and character-building process.
