I feel that's unfair, Tywin had a cold solid logic to his actions, he didnt give a single fuck about the peasents but he didnt really have a proactive disdain for them. Tywin was an actual pragmatist in that his horrible actions are motivated by clear aims and objectives, for example the horrific red wedding was ultimatly about ending a war against an enemy he was struggling to defeat and ultimatly worked really well.
Twyin would take on look at US politics and begin considering how exactly he's going to make himself or his chosen candidate president. If it doesnt pan out that campaign, he isnt going to bitch or cry but you're going to have to watch the fuck out for him campaign season after campaign season. Because he'll just come up with a new plan to get the common man to vote for him
Bobs closer to a Balon Greyjoy in that he will stick with his god-awful attitude and shitty idea's even when they're totally counter productive. Rob Stark offered him everything he wanted on a platter and his response was to shit the bed because he can't get over his absurd pride or bitterness. Or Maybe a Randly Tarley as he's a just a nasty cunt whose endless posturing is totally at odds with his reality.
