[ASOIF/Game Of Thrones] So, is Roose Bolton just trolling everyone?

Like, he is at the very least a rapist and murderer, but he is wearing a pink cloak when his family has rumors of skinning people. He speaks softly, which is a tactic used by people giving speeches to make people listen in to him. 

He doesn't drink wine in public, that kind of stuff. 

It all sounds like psychological warfare.

He doesn't drink wine and prefers hippocras because he's a bit of a health nut, by medieval standards (he also has regular leechings to remove "bad blood"). 

The pink cloak is meant to evoke a flayed body, and is his family's signature color; it wouldn't necessarily have the same girly-girl connotation that it does for us. 

But, yes, he is very adept as psychologically torturing people. When Jamie and Brienne become his guests/prisoners at Harrenhal, he gives Brienne very feminine clothes that he knows she won't be comfortable wearing, and serves them a steak that the now-handless Jamie can't cut, just to rub it in. He also seems to taunt "Reek" by sharing intimate details about his sex life to make Reek uncertain whether he can regard him as a friend.
