No apology necessary -- your rambling reminds me tangentially of Max Brod's decision to publish some of Kafka's writings after Kafka had explicitly asked him not to do so. The same question was at play -- whether one should interfere with the destruction of knowledge by its creator. Brod ended up publishing and for it we got Amerika, The Trial, and The Castle.

I can see arguments for both sides. Genius can be self-destructive and susceptible to manic episodes, and perhaps there's an argument where knowledge can forcibly be kept alive against its creator's will.

But it is his information, and as far as I can recall, its his right to get rid of it.
