Mr Mellon, I see I find you in another argument!
Perhaps if I can 'squeeze' a 'word' in between the two of you?!
Does everything happen for a reason? Depends on the nature ofthe question, which unfortunately went unspecified. One person gave an example of an asteroid strking him because he chose to sit at his desk to check for messages on Volconvo... I hesitate to say it for fear of being accused of having an obsession with the subject, but isn't that 'cause'?
I got the impression the original question was a sort of a 'fatey' question. 'Is there an intelligent design on what happens to people and why'?
I think that it is possible, but that the explanation for it would again fall down to the unconscious mind. It's not God, but a person's unrealised desires that steer him in directions he is not consciously choosing. That is the extent of fate, for me; the old idea of 'self fulfilling prophecy'.
