Navel gazing Lifeblood lyrics..

[who's responsible?]

Morning all,
Just spent a nice happy hour with Lifeblood on repeat, and have been sucked into a single line, and it's turned into (yet again) looking too deeply into a lyric.

Cardiff Afterlife; "For I witnessed splendour, and evil that no one saw"
OK, we all know the song's about you know who, and the rest of it really needs no questioning, but what evil is Wire on about? Or am I just navel-gazing on a wet Tuesday morning?
Any thoughts people?
