"Perhaps you already know it? You are a clever man, after all, Severus. You have been a good and faithful servant, and I regret what must happen."
"The Elder Wand cannot serve me properly, Severus, because I am not its true master. The Elder Wand belongs to the wizard who killed its last owner. You killed Albus Dumbledore. While you live, Severus, the Elder Wand cannot truly be mine."
And Voldemort swiped the air with the Elder Wand. It did nothing to Snape, who for a split second seemed to think he had been reprieved: but then Voldemort's intention became clear. The snake's cage was rolling through the air, and before Snape could do anything more than yell, it had encased him, head and shoulders, and Voldemort spoke in Parseltongue.
There was a terrible scream. Harry saw Snape's face losing the little color it had left; it whitened as his black eyes widened, as the snake's fangs pierced his neck, as he failed to push the enchanted cage off himself, as his knees gave way and he fell to the floor.
"I regret it," said Voldemort coldly.
He turned away; there was no sadness in him, no remorse. It was time to leave this shack and take charge, with a wand that would now do his full bidding. He pointed it at the starry cage holding the snake, which drifted upward, off Snape, who fell sideways onto the floor, blood gushing from the wounds in his neck. Voldemort swept from the room without a backward glance, and the great serpent floated after him in its huge protective sphere.""

VM did say twice "I regret it.". Isn't this almost the same as "remorse"? The second time he says "I regret it." to Snape, Snape has already been attacked and is dying.
Why would VM say "I regret it." to a dying man that poses no threat and VM has nothing to gain from anymore?
On the flip side, he says it coldly, and shows no feeling at the gruesomeness of the event.
JKR has stated multiple times that VM has no feelings, or I guess "good" feelings like love, sympathy, compassion, etc. So what is going on here? Is this just inconsistent writing or is there another reason it's written this way?
