@Zixis - Abaddon is not 'just like Horus' as he did not have the inherent might of a Primarch. Yes his soul would need to be destroyed by a powerful psyker, but it is safe to assume it only took the Emperor so much effort to destroy Horus' because he was a primarch. So it doesn't make sense that it would take someone of the Emperors power to kill Abaddon as he can never be as powerful as a Primarch, regardless of what pacts he has made with choas. Given the right circumstances any of the current legendary psykers would be capable.

@107 - I would say the same thing to you, Abaddon is not unkillable and no way it would require a psyker as powerful as the Emperor, as Abaddon is not as powerful as Horus, although admittedly alot more successful.
