The 10 most shocking 'House of Cards' moments, ranked

Frank and Russian President Viktor Petrov have been playing mind games with each other since they first met. And Viktor proved he can never be intimidated when he gave a smooch to Claire right in the middle of the White House with Frank a few feet away. The man has guts.

Frank believes in nothing but himself. And if you had any sense that he might believe in a higher power, that fizzled away when he spit on a crucifix.

Claire dealing with coming face-to-face with the General who raped her when they were in college was a landmark moment for the show and highlighted the vulnerabilities of even the most powerful woman in DC.

Frank showed just how evil he can be to get what he wants by killing Peter Russo, eventually making it easier for him to be vice president.

After the death of Russo, Rachel, a prostitute who was hired by Doug Stamper to help blackmail Russo, had been living under the thumb of Stamper. She finally escapes at the end of season two by bashing a rock against Stamper's head a few times.

After taking most of season three recovering from the beating Rachel gave him, Doug tracked down Rachel and murdered her — finally cutting off the link between Russo's death and Frank.

In one of the most shocking moments the show has ever given us, Frank pushed Zoe Barnes in front of a moving train after Zoe began to link the death of Russo to Frank.

The first time we ever meet Frank Underwood, he's racing to help an injured dog. Well, he has a strange way of helping, since he killed it with his bare hands.

While in the middle of his re-election campaign, Frank is shot by Lucas Goodwin. Meechum is by Frank's side and is also shot. While lying on Frank to block him from bullets, he shoots and kills Goodwin. Meechum dies, and Frank is rushed to the hospital. In a show full of surprises, we didn't see this one coming.
