I did not enjoy watching her beat him to death and it could definitely be for shock value but here are my thoughts: he was responsible for a traumatic, horrible event in her life. Kidnapped, held hostage, auctioned off, watched people die, the psychological torture she endured, etc...all because of him. She was not doing well mentally with all of the flashbacks and I think he just pushed her over the mental edge and she snapped. Preview for next week seem to allude to her not doing well with it at all which will be interesting to watch. Shonda is obviously trying to get us to believe Olivia is moving to her father's dark side but we'll see.
I also noticed Jake is ALWAYS EATING at the house. ha!
