It was HIS action and it was EXTREME HATE.
He should have said, "NEVER HARBOUR HATE LIKE I DID TOWARDS THOSE GIRLS."
What I think he was doing was putting it back on his executioners, the State of Texas, and us, the law abiding American citizens at the very end. Unremorseful and full of excuses to the end. If he were a man he would have worded it this way: "I hated, and so I have this coming to me. It is my own fault, you are justified."
That is how a true, repentant man, goes out. But I suspect we could not have expected that from such a scumbag on our US soil.
