The view from outside of aviation looks at the cause as:
"if not for" the initial engine failure .......
while the insiders view is:
"in spite of " a single engine loss of power .......
My initial questions are:
Why would the crew even think of taking action on any engine at a critical flight regime? I thought the concept was to take your time, aviate, navigate, communicate. Somewhere in this I would expect some aircraft configuration changes, but not turning off an engine until late in the process.
