Do you have any theory on how Craster managed to get his deal or whatever it is with the Others? Their usual MO seems to be ‘kill everyone&everything’. So why not Craster&daughters too, why does he get to live? Also strange is that Sam was warned an attack was imminent as the mutiniers took over. So Crasters Keep was save with all the Night’s Watch men there before, but the minute he dies an attack is on the way?Are the Others connected to Craster so they realized he died the moment it happened?

For their own, Unseelie, reasons, the Others are actually not that unwilling to take dominion over destruction, for at least the period of a mortal’s lifespan:

He remembered the hearth tales Old Nan told them. The wildlings were cruel men, she said, slavers and slayers and thieves. They consorted with giants and ghouls, stole girl children in the dead of night, and drank blood from polished horns. And their women lay with the Others in the Long Night to sire terrible half-human children…

“He was a wildling,” Bran said. “They carry off women and sell them to the Others.”

“He gives the boys to the gods. Come the white cold, he does, and of late it comes more often. That’s why he started giving them sheep, even though he has a taste for mutton. Only now the sheep’s gone too. Next it will be dogs, till …“ She lowered her eyes and stroked her belly.“

“The gathering gloom put Bran in mind of another of Old Nan’s stories, the tale of Night’s King. He had been the thirteenth man to lead the Night’s Watch, she said; a warrior who knew no fear. “And that was the fault in him,” she would add, “for all men must know fear.” A woman was his downfall; a woman glimpsed from atop the Wall, with skin as white as the moon and eyes like blue stars. Fearing nothing, he chased her and caught her and loved her, though her skin was cold as ice, and when he gave his seed to her he gave his soul as well.

He brought her back to the Nightfort and proclaimed her a queen and himself her king, and with strange sorceries he bound his Sworn Brothers to his will. For thirteen years they had ruled, Night’s King and his corpse queen, till finally the Stark of Winterfell and Joramun of the wildlings had joined to free the Watch from bondage. After his fall, when it was found he had been sacrificing to the Others, all records of Night’s King had been destroyed, his very name forbidden.“

Where I think most people in the fandom go wrong is they misunderstand the motivation and method of dominion; there are no examples of stable arrangements, formal treaties, or genuinely symbiotic relationships between men and Others. Rather, all the examples we have show such interactions as parasitical and corruptive, spiralling and intensifying at every step until they’ve wrung as many sacrifices as they’re going to get and turn on the person who’s served them. 

This is what makes them like the Unseelie: if you lay out milk, throw salt over your shoulders, and stay away from fairy circles, they might not kill you in your bed; but you can do everything right and they might steal your children anyway for some unfathomable, inhuman reason.
