She recalled all the humiliation she had endured as a result of him. When her husband was away, he nearly molested her in the same house. He thought he could do whatever he wanted because they were both around the same age.
To get him to leave her alone, she had to kick him in the balls. They had never had a constructive conversation since, and she didn't mind.
She wanted to strangle him and force him to beg on his knees until he bled. Her eyes glowed just thinking about it. She had to feed because of her demonic side. Those poor employees were the first; of course, it wasn't something she needed to continue doing.
She only needed to feed the other beast part of herself to keep control. She believed that with time, she would be able to fully control it, just as the demoness did.
