For one thing, if there's a water landing impending, the captain may announce it, including "...it is very important not to open any doors or move from your seats until floating attitude stabilizes and instructions are provided."
People are different. Some passengers probably found some comfort in the captain's announcement. Please submit a good statement to make during this incident...or suggest silence on the subject of the shaking.
This particular aircraft would now make a good test subject. Put it on a shake table, or maybe hang it from cable(s), and make the bad engine spin to quantify what the aircraft saw during the flight. Then put on some more time to see how much margin there was. Then vary speed and/or eccentric mass until something fails.
