In 1988, Yoshiki explained that the song is not about killing people as the title would suggest, but is a love song in the vein of a disgruntled married couple.[1] All 1,000 copies of the record sold out.[2] The cover art notoriously features numerous photographs of dead bodies taken during the Vietnam War.
A different recording of the B-side, "Break the Darkness", was included on the samplerHeavy Metal Force III in November 1985.[3] While a re-recording of the title track was later featured on the band's first album, Vanishing Vision. "I'll Kill You" was covered by French symphonic black metal band Anorexia Nervosa as a bonus track for the Japanese edition of their 2004 album Redemption Process and later included on their 2005 The September E.P. as well.[4][5]
