There IS that. Catelyn sort of did all of this to herself, and could have gotten Bran and Rickon killed, just for a little revenge.
Well, Cat did tell her son to follow through with marrying the Frey girl instead of his "love" (depending on book/show). Would Bolton and Frey still have turned on them then? Maybe. But then it would have been 100% on Bolton and Frey instead of the Starks sharing the blame.
As much as I am a "Stark", it seems like 95% of the time it's them getting in their own way.
Bran climbing the ruins when his parents told him not to (causing him to be in the wrong place at the wrong time)
Catelyn imprisoning Tyrion for attempted murder of Bran when the only evidence was the dagger (and, as Tyrion said, only an idiot would leave behind his own dagger)
Ned "dishonoring" himself at the wrong time (had he dishonored himself by taking up Littlefinger's suggestion and "supporting" Joeffry and out Cersei and her children a few years later instead of dishonoring himself by declaring himself a traitor right before his execution)
Robb breaking his treaty with the Freys
Catelyn setting Jaime free in hopes the Lannisters would release her daughters (such a foolish Hail Mary)
Robb executing Greystark (causing him to lose a lot of support in the North)
As much as th Starks get screwed in this show, a lot of the time they simply get in their own way. To paraphrase something Littlefinger said, "they act before they think." And it burns them a lot in this show.
