It's not as well explained as in the original. In that version, it's revealed that the gas station owner sired the head of the mutant family, and left him out in the desert to die. The mutants developed a truce where they'd trade with him for supplies he's bring in from neighboring towns. Unfortunately, those towns had begun to fold up. Hence the mutants got more desperate.
In the original film the station owner is a coward for numerous reasons but he doesn't send them to their deaths. In fact he warns them away from the desert. In the remake, he does send them to their deaths out of fear he'd been discovered. There's also no indication that he had any relation to the mutant family.
