Sí, SOY Español.(Spain from Europe, not Mexican,uh¡¡¡)
"Voy a comer el corazón"=(It´s bad spanish because it means =I´m going to eat the heart)He would say better "Voy a comer tu corazón"= I´m going to eat your heart
"Yo soy tu muerte"=I am your death
"Vete al diablo"= (It´s bad spanish because Vete al Diablo means =Go to Devil) I think he would say better "Vete al infierno" = go to hell.
Also , his Spanish is "southamerican" , with a Southamerican(perhaps Mexican) accent, not a pure spanish accent.
