Before Falling to Radicalism

"When in doubt, do not fear," Inquisitor Aurelius paced the length of the classroom, wondering how he had drawn the wretched duty of getting to speak to primary school students, "for the divine hand of the Emperor is always with you. As long as you remember this, you have no need to fear the mutant, the heretic, nor the psyker."

"So what if we think our mommy or daddy is a heretic," one little girl raised her hand to ask.

"Then you should tell someone who can do something about it dear one, like the Holy Inquisition," Aurelius bent down and patted her on the head, his chain of heretic skulls dangling alongside. He rose and continued his walk about the room, "you must always be vigilant that you do not let your minds become open to new ideas and corruption. A closed mind is like a fortress, and bars entrance to the evil depths of corrupt heresies."

"But mum said that we should always be open to new things," one boy in the front row timidly said, as if fearing he would be struck down on the spot.

"Really," Inquisitor Aurelius raised his eyebrow, and moved over to the seating chart, taking down the boy's home address and name, with a notation to purge the family for heresy, "well your mother was wrong."

He looked up from his notations and continued about the room, waiting for the next question, and not finding one, he continued with his speech, "The God Emperor is Love, for he would not even fight back against the traitor Horus until Ollian Pious was so casually murdered before him. That was when the Emperor slew Horus, and was interred in the Golden Throne to this very day. And in the Golden Throne, he is able to watch over us for an eternity."

"But isn't the Golden Throne an evil piece of technology from the Dark Age of Technology," one boy asked, who had been doodling the whole time.

Inquisitor Aurelius marched over to where the boy sat, and looking down was aghast to see the eight pointed symbol which he would not have expected here, the star of Chaos. He cleared his throat, and spoke in a rich timbre he had yet to use, "Children, let this be a lesson to you. The heretic can be anywhere, even here. This boy not only questions the God Emperor and the teachings of the Ecclesiarchy, but also draws damnable sigils."

With those words he withdrew his laspistol, and fired a single shot between the boy's eyes, dropping him upon his desk lifeless, as the children began to scream. Holstering his laspistol, he boomed above the screams, "Do not fear at the holy work of I, a mere servant of the God Emperor. For the threat of heresy can take many forms, even one you considered to be a friend and companion."

He walked over to the seating chart, and next to the dead boy's name, made another notation to purge the family for heresy.

Author's note: I'd call this over the top, but this is exactly the tone of Warhammer40k. Lighter actually, since he didn't order the place bombarded from orbit by an Imperial fleet.
