Emo stems from the Washington D.C. Hardcore Punk scene. It is a genre of music pioneered by the band The Rites of Spring. The fashion is based on the 1950's "geeky" type, along with a mix of "Indie Rock" attire.Goth stands for Gothic Rock, and it is the offspring of Post-Punk, which is the original Punk Rock scene, but with reduced aggression, earning the title "Positive Punk".Gothic Rock's musical elements are the combination of Post-Punk, Psychedelic Rock, Glam Rock, and Horror Film scores.Gothic Rock originally was known as "the Batcave sound", after the world's first Goth nightclub called The Batcave, owned by the Gothic Rock group Specimen.
I'm not positive so don't rely on my answer...but this is what i think. I think emo people are very emotional and tend to be depressed. A lot of them do self harm (burning, cutting)...I think some of them are sucicidal. Goths wear dark colors, and they are interested in death, but they are generally happy people. But I don't know for sure.
