The human-shield-junkie thing was not Ennis' Max. Idk who it was
I dont think Ennis has enough self awareness to try some commentary on toxic masculinity.

The only thing i can think of is that the guy mentioned that he was there on illegal (drug related?) business dealings that werent prostitution. but thats not very much to work with (despite Frank's er forceful anti-drug stance) The closest situations i can recall with women were trafficked women. Even the honeytrap was alone in a snowy forest full of dead guys.
Ennis' women were usually on extreme ends of the 'victim-villain' scale

Barracuda jn general was wack.
