Interference
Sam didn't care if he would turn into a monster or something else for drinking human blood, but he is sure that this is the best way to deal with her at the moment and this is also the most painful way to deal with her.
After all, she is good at sucking the vitality of the people with her flames.
She kills them with the most torturous of the methods, so he wanted to see how she would act in such a situation. He wants to see her expression.
He used his other hand to remove her veil.
She is neither beautiful nor ugly. Her facial features are average. She would easily blend in with the crowd.
As Sam is enjoying her agony and was about to finish her off, he felt a weird pull over his body, and both of them separated.
At this moment, his instincts are too dangerous and he is in complete vampire mode. If any other players are beside him he would either feast on their blood or kill them directly.
