not bad not bad
If you didn't believe in fate then you would be fated to have a ridiculous conversation about fate which would eventually lead to the fated death of you and your friend. The fact that he didn't believe in fate meant that all of the preconditions for that conversation were there and so he died exactly when fate planned him to die.
I think you might have said something like that somewhere in there anyway but i wanted to type it out myself so I could get it right in my head.
If the author happens to read this could you also read my review of the 29 day war and tell me if I was right.
