The 6 of them bowed and said, "We greet Count Xigger."
Their greeting was respectful and deferential despite them knowing that he killed their family and friends and everyone that they cared about. He looked at them with a sneer. He can see the hatred hidden deep within their eyes. He doesn't need to use his authority over them to know what they truly think of him. He has been in their shoes in the past so he is intimately familiar with their loss.
He briefly entertained a show of strength to discipline them and put them in their place. It is not needed since they will obey him absolutely regardless. But he is still giddy from his earlier indulgence. He wants to shed more blood.
"Maybe just a little." He thought to himself. "It doesn't hurt to show them that planning for revenge is futile."
The voice in his head chuckled and said to him, "You have become the devil that you hate."
