Moore is wrong - but he comes from a place of misplaced principles. Within his mistaken beliefs he's ethical.
The stalker - on the other hand - comes from a place of darkness and lies. Big difference.
As I stated above, McGinnis has all the classic signs of a serial stalker. His moving to Wasilla, esp. next door to the object of his obsession, will only serve to increase the delusion growing in his head.
