The Walking Dead: 10 Worst Things Alpha Ever Did
5. Antagonising A Grieving Carol
Out of everyone Alpha comes into conflict with, Carol suffers the most emotionally. Killing her adopted son Henry in the final act of the show's ninth season, she spends much of season ten feeding off and utilising Carol's grief to her benefit.
First, there's a meeting Alpha has with Daryl, Michonne and Carol at her border, which ends horribly when Carol tries to shoot her. Later, Alpha toys with her and forces her to accidentally lead her friends into the aforementioned cave.
Even in death, Alpha haunts Carol, causing her deep, psychological damage unlike any villain before or since on the show.
Alpha's done plenty of terrible things to various characters - including nearly killing Daryl just before her own last moments - but the pain she inflicts on Carol is one of her worst achievements.
