which works is this quotation from? --- Dark mind, dark heart

[konohazuku]

Does someone know?
"Dark mind, dark heart" is quoted from some literature works?
Or someone said?
I wonder from "Machbeth" of Shakespeare, but I don't know.

hmmm...could be...it does sound like Shakespeare...though doesn't seem to quite be Mcbeth...but i've read it, and am not quite sure where it would be...sounds more along the lines of one of his other tragedies...maybe Titus Adronicus or something like that...I'll see if I can find it.
