Sister Argenta: The Emperor's most Pious Heretic
Sister Argenta murdered Lady Theodora, her reasons for doing so are irrelevant to the conversation.
Lady Theodora was a Rogue Trader, protected under the aegis of a Sacred Warrant of Trade. A Warrant signed, not simply by some Highlords of Terra, but by the Emperor Himself, in His very own blood.
The murder of Lady Theodora was, thusly, an insult to the God-Emperor of Mankind. She placed her own judgement above the judgement of the highest Divinity in the Imperium.
Argenta’s heresy is not impiety. It is presumption.
The arrogance to believe that her judgement is purer than that of those placed above her by Sacred Writ.
She is a cautionary tale. That no matter how pious the purity of your belief, it doesn’t mean you know better than your betters in the Imperium.
