Since you don't know what is simply in parallel or simply in series then you should stay away from the mains voltage that can kill you or other people.
Here is the corrected schematic:
The 1M resistor discharges the capacitor when the circuit is turned off or is not connected to anything. Then a repairman will not get zapped by a charged capacitor.
The location of your 1M resistor did not do anything unless the mains connection is shorted which will never happen.
EDIT: I think if a repairman does not discharge a high voltage capacitor himself then he deserves to get zapped.
Then he might learn sumpthin.
