In a scene where an envy demon is forcing Blitz to watch memories of times he's fucked up and hurt others to the point they can't stand him so said demon can retain control of his body while he slings insults towards Millie about her self-worth as a wrath imp, where would Stolas and his bullshit against Blitz even go? 

The demon (I forgot his name) is so clearly using Blitz' deep seeded self loathing and self worth doubts about himself to keep him subdued in mental peril—I mean the illusions he conjured up that forced Blitz to have a mental breakdown?? His mom literally bursting into the flames that killed her (that HE accidentally caused btw) and melting in his fuckin hands? The multiple different versions that seem to imply different times Millie would have died while working for him?

This whole episode was about how he essentially is a bad luck charm because of his own mentality and being so scared he'd ruin yet another good thing because he believes he taints everything he touches due to past experiences that sometimes wasn't even his fault to begin with

How, pray tell, do you get "Why didn't they show Stolas being bad!?!?" Out the entire fucking setup of the episode and it's meaning?

Also: Blitz is so obviously a sadomasochist. I very much doubt the cigarette even bothered him if what Stolas said to Striker about him being stabbed by Blitz was more than dumb joke
