That's subjective. This hits differently for everyone. Some of us, this was really hard to watch... Moreso than others.
Meeting Negan for the first time is a hair's breadth tie. Like, both are bad. Negan is bad like, hopelessness consuming you, the closest I've ever felt to the characters where I shared the "I'm going to die." feeling. This one... this little girl... You put yourself in the woman's shoes (I forget her name) and you have to kill this little girl who has been so traumatized by the world, that she's now suffering acuste dissociation disorder and has lost all connection with reality. She's as much a danger to you as she is herself. You don't want her to die and come back a zombie, so you have to do it yourself. Because no one else can. Before you pull the trigger, you gotta lie to her to look at the flowers. Her disconnect is so strong that she doesn't realize what you're doing, and while she is so damaged, you know that this is the best level of innocence her mind could manage to protect itself. She's still in there, just walled in. She's not gone... Just needs serious therapy. But that's gone now. And the only therapy is a bullet to the head by your unwilling hand who took her in like a daughter.
Holy crap.
