Contextual Analysis of "i'm don't know if i would save you. i would rather see the sadness in your eyes" in Lyrics

i need her heart. and i it beating. i need her head. and i need it bleeding. don't let me get in your head. i'll make you wish you were dead. don't let me get in your head. i'll make you wish you were dead. if i repeat myself i apologize. it's hard to see with clouded eyes. you owe a debt. i want what's mine. pay with your life. grit my teeth more than i should. when i swallow i taste only blood. i hate myself more than you ever could. when i swallow i can taste your blood. i still see her when i close my eyes. i still see her when i close my eyes. if i repeat myself i apologize. it's hard to see with clouded eyes. you owe a debt. i want what's mine. pay with your life. if your life depended on me

as i let you die. save your apologies unless you're on your knees. no need to beg and plea. grit your teeth
