Terry Pratchett dead. And I wonder.

Author Terry (Diskworld) Pratchett is dead.  (28 April 1948 – 12 March 2015.)

Given his strong and persistently outspoken opinion in favor of euthanasia (they call it "right to die") -- did Sir Terry off himself? Whether he did or not -- is the unquestioning silence of the press further evidence of pro-euthanasia bias? 

Pratchett:  atheist, egotist . . .  suicide? Doesn't sound like a very creative end for a guy who would have wanted to be known as creative. May the God in whom he did not believe have mercy on his soul.
