[American Psycho] Did Patrick Bateman really kill people?

Or was it just something that he made up?
gpt
Part of the main points of the culture at the time is that everyone only cares about themselves. This is shown by everyone cheating on everyone, no one learning each others names, and a bunch of other behaviors. It is entirely possible that he did actually kill all of those people and everyone that knew didn't care because it would cause more trouble for themselves.

The lawyer: What does he have to gain from turning Bateman in? It's believable that he is just playing dumb in the restaurant not to build up a fuss.

The realtor: She doesn't care about the bodies at all. She just hired a person to clean up the place. If the news about the murders got out, the property price would plummet. Price plummets and she looses out on a fortune made off of the commission made from selling Paul Allen's apartment (which is nicer then Bateman's). She knows who he is when he returns to the scene of the crime and that's why she tells him "you should probably just leave"

The thing is, in the movie, everyone is an asshole looking out for their own self interest. At least Bateman tries to be normal.
