Your talking about 1 being vs several hundred thousand if not 1-2 million; Deathstar IS NOT just a planet destroying cannon, it is a shielded, armored, FTL equipped (max speed over 1million X the speed of light) battle station containing an ARMADA of planet leveling battle ships AND nearly countless 1-6 man star fighters and marines and soldiers! 1 dude with some tech vs a INTER GALACTICLY MOBILE battle-station with hundreds of thousands of planet leveling battle cruisers AND a nearly countless battle force! An your hedging your bet on THE SINGLE BEING?! Can that 1 being stop or evade incoming fire from EVERY DIRECTION all at once? If not IT WILL LOSE!
