The dude would have Capgras Syndrome (delusions of a negative double)

With this syndrome, a person is convinced that someone from his close environment (spouse, parent, child) has been replaced by an outwardly identical, but in fact completely alien person - a double (impostor).

Features:

The persistence of delirium. The belief does not disappear even if there is convincing evidence to the contrary. The paradox of perception. Often, a person is able to recognize a face, but does not experience an emotional response to it related to intimacy or trust. Related delusional ideas. Thoughts of harassment or a threat to life may be added.

(Just like in postal 1, he considers most people to be life-threatening. )

An angel, on the contrary, has ( but the opposite ) Fregoli syndrome (delusions of a positive double)

The essence of the disorder is that a person is convinced that different strangers around them are actually the same person they know, who is deliberately making up and disguising himself in order to remain unrecognized. This is often accompanied by delusions of persecution.

Features:

Violation of information integration. It occurs due to a malfunction of neural networks connecting visual perception, emotional reaction and memory.

I guess the Angel has Prosopometamorphopsy This is a rare visual perception disorder in which people's faces appear distorted — for example, deformed, with deep wrinkles, unnaturally stretched or covered with furrows. In some cases, such distortions may resemble "demonic" features.

P.S — disorder is associated with damage or abnormalities in different areas of the brain (temporal, occipital, parietal and frontal lobes), as well as with epilepsy.

Also visual hallucinations In some conditions (for example, alcoholic delirium, some infectious psychoses), a person may see non-existent images of mystical creatures, people, or entire scenes. The key sign of a true hallucination is complete conviction of the reality of what you have seen and the absence of criticism of what is happening.
