Here are excerpts from videos Virginia Tech shooter Seung-Hui Cho sent to NBC News. Cho apparently mailed a package containing the videos and other materials from a Virginia post office in the midst of his rampage, at 9:01 a.m. Monday, April 16, 2007.
"This is it. This is where it all ends. What a life it was. Some life."
"You had a hundred billion chances and ways to have avoided today. But you decided to spill my blood. You forced me into a corner and gave me only one option. The decision was yours. Now you have blood on your hands that will never wash off."
"I didn't have to do it. I could have left. I could have fled. But now I am no longer running. If not for me, for my children and my brothers and sisters that you (expletive). I did it for them."
"You just loved to crucify me. You loved inducing cancer in my head, terror in my heart and ripping my soul all this time."
"You have vandalized my heart, raped my soul and torched my conscience. You thought it was one pathetic boy's life you were extinguishing. Thanks to you, I die like Jesus Christ, to inspire generations of the weak and the defenseless people."
"Do you know what it feels like to be spit on your face and have trash shoved down your throat? Do you know what it feels like to dig your own grave? Do you know what it feels like to have your throat slashed from ear to ear? Do you know what it feels like to be torched alive? Do you know what it feels like to be humiliated and be impaled upon a cross and left to bleed to death for your amusement?
"You have never felt a single ounce of pain your whole life. And you want to inject as much misery in our lives because you can, just because you can. You had everything you wanted. Your Mercedes wasn't enough, you brats. Your golden necklaces weren't enough, you snobs. Your trust fund wasn't enough. Your vodka and cognac wasn't enough. All your debaucheries weren't enough. Those weren't enough to fulfill your hedonistic needs. You had everything."
"When the time came, I did it. I had to."
