Ramsay: *violates Theon's trust*
Ramsay: *violates Theon's body*
Ramsay: *violates Theon's sense of self*
Ramsay: *violates Theon emotionally with sexual overtones*
Furthermore, where is the violation in the first place? Sansa consented to the marriage and it was duly consummated. She didn't say no at any point; she didn't even resist. True, Ramsay's insistence on having a witness was a little unusual, although hardly unheard of in medieval times.

Audience: HOW DARE THEY THIS SHOW HAS GONE TOO FAR
"Testimony of witnesses at Catherine's later trial for divorce from Henry VIII described the Couple as escorted to their bedchamber, undressed, put to bed together and the curtains around the bed drawn, while the witnesses (male and female) waited the night in the room."
Let's face it, making Theon watch while he concluded the marital process isn't even in the top ten most sadistic things Ramsay Bolton has done on the show. And where was the outrage when Khal Drogo was sealing the deal on his marriage? Ah, but then, Khal Drogo is more attractive than Ramsay Bolton.
