I think this chapter is an allegory of "what is wrong feels good" he wants to eat steak for breakfast and have lots of girlfriends because it is wrong to do so (in a way). It is like speaking of free will, in the sense of once you stare at the abyss you start to wonder what's deep inside. We play a dangerous game every day to fight or indulge on those desires. Is like saying I want to let loose for once and not think of consequences. Therefore, you wanna watch a crapy movie just to hate it, to be free in a twisted way.
I think the date (the one people refer in the comments) was a way of shoving humanity on to him so he could have something to grieve for, like he's doing right now.
Seems to be very complex, but I'm starting to think that the chainsaw man is the antithesis of the control devil. He's pure chaos, over the top movie like persona. An exaggeration of wildest dreams, revered for being the unexpected thing that makes us humans, but deeply feared at the same time, because we don't want to lose control.
