Cho was a troubled young man, which is a given. The system identified him as such but didn't followup to insure he got the help he needed. As children we didn't think teasing and humiliating other kids was harmful...it was all in good fun...unless you were on the receiving end. This poem was written out of grief for those he killed, but also as atonement for those who failed him by not getting him the help he so needed...thus the lost soul. The loss of a single life is horrible as there is no way of knowing what contribution to society was lost by the loss of that single life.
