Reminder that he is a malignant narcissist, and is biologically incapable of accepting blame, responsibility or personal faults. As per the Narcissist’s Prayer:

That didn’t happen.

And if it did, it wasn’t that bad.

And if it was, that’s not a big deal.

And if it is, that’s not my fault.

And if it was, I didn’t mean it.

And if I did, you deserved it.
