Can Erebus or Kor Phaeron just die already?

I need one of these jackasses to die, preferably horribly and poetically. The other Chaos crew at least have SOME redeeming qualities:

• Abbadon can live cause he’s gotta be the big bad(ish) dude and actually has some redeeming qualities.
• Lucius can…keep doing his thing. He’s in his own little repeating hell.
• Typhus can continue being a dirty weird little guy. And Nurgle would just resurrect his petty ass anyways.
• Khârn is simply too angry to die and was honorable at one time before he got space rabies.
• Ahriman is actually pretty awesome and he’s at least loyal to his legion, even thought he screws everything up anytime he tries to fix something.

But…Kor Phaeron and Erebus? Nope. Complete A-holes without a single redeeming quality. The mere fact that they’re still skulking around in M42 is a travesty.

I don’t care how the BL authors do it, it’s just gotta be painful.
