I disagree with his assessment of what is involved in the scenario.
In respect of the 'fat guy' ...... he is in no danger without my action ..... so if I do push him that is a deliberate act on my part that is guaranteed to cause his death.
I am not prepared to commit the murder of an innocent even if it saves others.
On the other hand, if this 'fat guy' was the cause of the situation, ( had interfered with the train or tied the five to the railway line etc) then I would have no compunction in dropping him in front of the train in order to save the five.
.... it is a false test ....
.... of course the above also implies that I would not have changed the course of the train in the first part to kill one innocent in order to save the five ......
