If the Emprah hadn't killed Horus it is likely that they would have taken Terra and thus the entire imperium. He did this in 7 years and killed 2.3 trillion people. Failbaddon had 10,000 years and has yet to take the 2nd most fortified planet with the help of Daemon primarchs and without having to face any Loyalist Primarchs. Even the Severan Dominant has managed to hold its own against the Imperium, a WAAAAAGH, and the forces of Chaos. God knows how but they have.
