Well they may as well pack up and end the show/ books now then. If the general aim is to kill off everyone that is likeable, and you're meant to be end up rooting for the complete twunks that are left, then it's going to leave everyone pretty disappointed with the way the series will pan out, in my opinion.
I don't think you're "meant" to root for anyone. One of the themes for the series is "the nicer you are the harder you get **** over" and that shitty people do shitty things - occasionally getting **** over by someone shittier.
