(Book Spoilers) Roose Bolton A Hero?

[Winterz]

Except Vlad defeated the Turks to free his country from their oppression while Roose got his own country into the shithole and allied with the Turks.

[Tenshi]

To play devil's advocate though:

Roose Bolton recognized what others didn't. Renly's death and Stannis defeat left an alliance of Lannister, Stormlands, Crownlands and the Reach, with support of Dorne, VS North and Riverlands, VS Iron Islands. And the Iron Islands were for all practical purposes also helping the Lannisters.

Add that the North was overrun, the Freys and Karstarks likely lost as allies, Jaime free while the Lannisters still held one or two major Stark hostages. And finally, the reason they went to war was to rescue Ned. Which was by now impossible, obviously. Note, I'm not sure on several of these... wasn't the Duskendale scheme already done before Jaime escaped?

Given the situation, continuing the war was futile, simply sacrificing tens of thousands of lives and destroying the remains of the Riverlands...for what? A lost cause, a title, a halfbaked claim of independence that would lead to nowhere.

As such, for the sake of the North, suing for peace was the right move. And Robb would never due that with the Lannisters for personal reasons. Thus, Roose, as second-in-command, had a good reason to negotiate a truce himself. This could be considered heroic from some point of view: defying your king and risking your head, for the good of the people. For those who question that, I remind you of the BwB: they oppose the Starks just like they oppose the Lannisters, as neither side cares about the smallfolk, who are the ones paying most dearly.

Of course, even with that reasoning, one still has to admit that Roose abused the situation for personal gain; the large scale butchery in which he wiped out most Northern main forces, were of no use for that goal, only for his own plans to become the new overlord. And the Red Wedding's fallout made a civil war in the North nearly unavoidable. His choice to make a psychopath his heir to the North doesn't speak for him either. He doesn't care.

Final point that we should remember of Roose: he's not a maniac. He strongly disapproves of Ramsay's actions, and as I see it, he takes little pleasure in the Red Wedding (unlike Walder Frey). It's not in his character, it's a mess: while he has no problem with cruelty and massacre, he has enough restraint to do it in secret. While this doesn't make him a nice guy, for all sense and purpose it does make him a far better person. And far more dangerous, of course.

In answer to the OP, yes he is.

[Scipio Africanus]

Good people can be terrible rulers, and terrible people can be good rulers.

And some people are both terrible as rulers and as people. And guess what, Roose is just that.

Vlad is seen as a hero to some of the peoples of his region in Transylvania because of him deteating the Turkish Empire and his cruelty put,

Vlad was a hero to some Wallachians because he kept his country independant from the infidel Turks. As @winterz said Roose would've betrayed his country and would've allied with the Turks if we're making a parallel here.

If anything Roose is Benedict Arnold.
