Sure people say that. But what if love imposes an undue burden, to force someone to live when they should die, to force them to spend every moment in torment to keep them in the presence of the lover? What if love isn't letting them go, but a trap that shackles good deeds and allows bad intentions to run rampant? What if the purest love cannot overcome the purest evil, but is instead subservient to it? Is this where sacrifice becomes necessary? Sacrifice over love?
What is love?
