She helped his father kill those girls after all...

Poor Abi.

She was manipulated and never wanted any part of it. She is not a murderer, she is a victim.

She is a victim. But I could see her killing again. Plus I think Her and Hannibal faked her death so ..

Both.

She was groomed and manipulated her entire life by her father and now Hannibal. She did what she felt she had to do to survive.

Both

Agreed, both.

Capable of being a monster, definitely, but mostly a victim. I think she's a killer based on circumstance and coercion more than anything else, and would choose not to partake otherwise.
