[WH40K] Okay, Abaddon here, I can't figure this thing out

Yo, fool. Yeah, I bet you thought I'd be speaking slightly differently. Well, you were correct, lowly moral. Continue to cower behind your pict screen, you may yet survive another pitiful night in your broken Imperium (*spits*).

Before I conclude with flaying you alive in the Garden of Slaanesh for an eternity...I have a question for you. Answer correctly and I shall grant you a quick death. Why then, during the Siege of Terra, didn't Horus the beloved Warmaster, simply launch virus bombs and destroy the loyalist fools with ease? If I recall the events correctly, we were in control of the air and we must have had access to virus bombs or at the least enough firepower to destroy Terra from orbit. 

My question is, why did we subject ourselves to a prolonged siege when there were other options?

Do you have any fucking idea how important Terra is? You want to virus bomb that?! You don't take the Emperor's Golden armour then proceed to go "Yeah.. They'd make good toilet paper." You fucking wear it! You own Terra and it's people, in tact, you own the universe. No wonder they call you Failbbadon, you'll never amount to anything Horus was, especially without your arms.
