The title phrase and "Shot, shot, shot, shot, shot like a bullet" hook together helped form a song skeleton that Braide developed further with Vickers at a writing session in Braide's studio.^[2]

"The Boy Who Murdered Love" has received positive reviews from critics. Robert Copsey from Digital Spy wrote that "It all adds up to a smart, sophisticated pop tune carried off with enough conviction to discourage any future bad boys hoping to give her the runaround."^[1] Fraser McAlpine from BBC Radio 1 gave the song four stars out of five, saying "I'm just saying there's room for improvement. Constructive criticism, y'see. And on the plus side, well what a lovely chorus you've made. It really is a wondrous thing, because at the beginning it is all jabby and urgent and angry, and at the end it becomes floaty and mournful. That's very good indeed, especially coming after the purring verses. So well done there."^[3]

The music video for "The Boy Who Murdered Love" premiered on MSN on 3 June 2010.^[4] It features Vickers in a house reflecting over her boyfriend, who has recently broken her heart. Throughout the video, various cartoon images appear, including lips, hearts, water and arrows. Cartoon text is also seen to accompany the lyrics "pain", "hurt" and "love".
