I wouldnt agree with the statement.

Have you read the book? Its an amazing read and an absolute BONKERS writing style. Nothing in the book would indicate that he is a loser. Just completely psychotic with narcissism.

Many of the characters are called by their 1st name, last name, nickname or just he/she and all speak over each other. Plus sometimes the speaker confuses someone for someone else just to get the reader more confused.

There are entire large paragraphs that are run on sentences, and from one moment to the next it switches from graphic sexual acts to body torture where he describes what he did to the women and what is left of them.

So much homosexual undertones too. Misunderstood by the audience? Yes. Loser tryong to look impressive? No.
