Everything stated here is right on target. As a therapist I have had to read and clinically process manifestos and various writings of persons before and after their death. You never get a well written, well documented "reason" for what the person did. 99.9% is illogical because it is wrapped in the reality of the writer, which only they understand.
As to releasing this information, it has two results. It makes a lot of hurting people who are already asking "Why?" hurt even more because there is no comprehensible answer. Second, emotional healing is like a cut; over time an emotional "scab" forms over the heart and soul. When a great deal of ambiguous information is released it tears the "scab" from people who are suffering in unimaginable ways, and they have to start the healing process all over again . . .
