I think the lyrical reversal from murderer to victim in Bury Me in Black is more a reflection on fame, the panopticon, and the concept of having a legacy. It's a poke at what it feels like to re-enact songs written by a different, younger, hopeless version of yourself, and it being consumed by an audience. That's in no way a knock to the audience or to suggest the band doesn't like us! But it is a suggestion that things are purposely changed because it would be Significant if they were.
This is especially given how lyrically obsessed Conventional Weapons was with the industry (Boy Division and Kiss the Ring come to mind, there's more but it's after 1AM here) and how lyrically obsessed Danger Days was with the concept of legacy itself. NaNaNa claims to not care, Only Hope talks about memory, Save Yourself is a musical version of the infamous "If we never play a show again, keep yourself alive," and Vampire Money is a very cheeky acknowledgment of the many trends they started/perpetuated.
TLDR: I think tying Bury Me in Black up only in the narrative of the Demolition Lovers just makes it too neat and tidy and does a disservice to the way the band has been approaching the the reunion tour ¯\_(ツ)_/¯
