"Khi nhắc đến bạo lực, bắt nạt học đường, nhiều người nói “đây là chuyện trẻ con”, “đi học ai chẳng thế”… Nhưng nhiều vụ việc có hậu quả không thể khắc phục đã xảy ra như bị thương, mất mạng vì đánh nhau, trả thù. Cũng có những trường hợp không tổn thương thể xác, nhưng vết thương tinh thần vì từng bị bắt nạt vẫn còn cho đến khi trưởng thành, thậm chí đến hết cuộc đời. Tháng 8 năm 2019, một người đàn ông 69 tuổi trong buổi họp lớp đã rút súng bắn chết một người bạn từng bắt nạt mình 53 năm trước. Nhiều người thả “haha” trong bài đăng về chuyện này, nhưng khi nghĩ đến việc mỗi lần say rượu, người đàn ông này đều nhắc đến chuyện từng bị bắt nạt, chắc hẳn sẽ còn ít người muốn cười. Và ở tuổi 69, ông ta vẫn yêu cầu người kia xin lỗi, sau đó nổ súng khi không nhận được lời xin lỗi đã chờ 53 năm. Theo các nghiên cứu, 40% người trên 25 tuổi từng bị bắt nạt đều gặp phải dấu hiệu về tâm thần, 15% số người từng bị bắt nạt nghĩ đến chuyện trả thù khi lớn lên. Không chỉ vậy, 5% số người từng bị bắt nạt trở thành kẻ đi bắt nạt để thỏa mãn những tổn thương tâm lý."
