Quick SCP idea: A de motivational poster that features pictures of various horrific moments from human history (changing regularly through supernatural means), with the caption "And that's terrible" below.
Those who look at the poster repeatedly find that they no longer feel a conscience, and are willing to commit immoral acts without psychological repercussions.
Forgive my Noobness, but how can I resize the picture to better fit the article?
EDIT: Decently drafted version now available at the Sandbox!
