That's fine. Coming up with multiple answers is useful, and then you can either explore all of them or you can filter.

For example, I think that you are jumping down too far with your first responses. Snowden leaked because:

1) he had access to it - exploring the why's here will improve your security

2) he was appalled at what he saw - exploring why's here will lead to discussion of whether he was right

I can, in no more than 5 whys, get from ANY problem back to my own personal hobby horse issue.

Typically you'd avoid subjective analysis in 5 why's so transform traitor into person and too much into empty string and in the third answer it should probably have "was perceived by Snowden as the most likely"
