The pilot had a similar route to the one flown by MH370 on his home flight simulator according to the ATSB report. From Reuters:
"Six weeks before the aircraft’s disappearance, Captain Zaharie Ahmad Shah used his home simulator to fly a route that was initially similar to part of the route flown by MH370 up the Strait of Malacca, with a left-hand turn and track into the southern Indian Ocean, the ATSB said in its report."
It's highly likely that MH370 was the result of pilot suicide.
