What/where is the best way to kill the future Kaiser Wilhelm II where:
1) He does not have any of his offspring yet
2) Prince Heinrich has had as much of his eduction
I am trying to get, for a time line I'm thinking of, a prince Heinrich as much like OTL as possible, meaning had a similar childhood and upbringing, and place him on the throne.
So Wilhelm needs to die no later then May 1881.
The problem with this is that it results in Prince Heinrich being the heir from birth. He would, I assume, receive a hugely different upbringing as a result. He would not be allowed to join the Imperial Navy cadet program, most likely.
Would he still be humble, open, rational, diplomatic person he was, if he were raised under the pressure of being crown prince?
