Today in "this is why people think I'm weird":
I'm rewatching Suicide Squad (love Harley in that movie, Margot Robbie is amazing in that role), and me and my spouse ended up discussing how much Arkham failed her.
She should *never* have been put in a position where the Joker could manipulate her the way he did, the higher-ups should've made sure that there were supervision *and* that there were debriefing with a mental health professional that knows and understands this kind of psychology.
