This quote is associated with Joshua Graham from the Fallout: New Vegas add-on Honest Hearts, released in 2011. The line became especially popular in gaming communities and meme edits because it sounds stoic, ruthless and instantly recognizable even out of context. Over time it spread beyond Fallout videos into reaction posts, anime edits and montage clips where someone stops hesitating and acts. Its staying power comes from how short, quotable and adaptable the delivery is in both serious and ironic formats.
