I dealt with the same thing many times and it really helped me to understand what a malignant narcissist is: https://mindpsychiatrist.com/how-to-deal-with-a-malignant-narcissist-at-work/

Malignant narcissists see other human beings as nothing more than puppets. If a puppet isn't doing what they want (usually after some emotional abuse) they'll toss it aside and just get another puppet that will. These people are usually incapable of feeling empathy for others.

Sounds like your VP is a prime example.
