Summary: Flesh of my flesh, bone of my bone. It is all for them.
Character Dynamics: Vader/Luke/Leia
The love of a Sith Lord is a powerful vim. It is a poisonous asset, beautiful yet lethal. Many may preach that one possessed by the dark side of the force is unable to love, that the seduced are cruel and unfeeling. No Sith could possibly care for another mortal, let alone a naive child. They are wrong.
The love that I feel for my children is not something I understand, but is simply automatic. I do not govern it.
My son claims that I do not love him. Obi-Wan has poisoned his mind with the dogma of the Jedi, the mark is lucid. I do not identify my old Master through the boy's vacant words or the manner in which he manipulates my lightsaber. It is the concoction of defiance and hope beneath the pigment of his eyes.
My daughter claims that I merely acquire her to subjugate even the most distant star systems. I know no other way to express the compassion and empathy that comes with being a parent. I sacrifice my aficionada, slaughter myriads of souls, and conquer bloodied lands for them both. Their happiness is all I desire. By ruling juxtaposed to me, I would hope for them to find pleasure in annihilating all opposition.
But that is not what they want.
The sapped principles of the Jedi have infected my son, rotted him inside out from the core. Rejecting my affection is what engenders my daughter's happiness and strength.
To show that I care, I am prepared to wage a long, perilous war.
The love of a Sith Lord is cruel, curious, and absolute. It is the love I attempt to bestow upon my son. My daughter. Flesh of my flesh, bone of my bone. It is all for them.
