No. He made it clear what his reasons were for why he did what he did. All of these questions can be answered by reading the manifesto.
This is why I think it is a mistake to try and suppress not just his manifesto but the manifestos or other forms of communication from ANY person who commits these acts. It's insulting to me that any government tells the world not to read it but then allows and even encourages "journalists" to select specific parts of it to "report" on, often taking things out of context or adding their own spin, or using it to promote their own beliefs or agendas.
If the manifesto is truly the senseless ramblings of a madman not worthy of discussion or debate, I can read it and figure that out for myself. I don't need nor do I accept someone else interpreting the contents of it for me.
All imo.
