Yeah I was gonna say that. He was famously single his entire life and is speculated to be one of the first historical examples of an asexual and aromantic person.
They're not fictional, they're mythical. Here's the difference between reality, fiction, and myth: Fiction is made out of the rearranged parts of reality. Myth is made out of fiction that people thought was important. And reality is made out of myth that people took too literally.
The Greeks didn't understand asexuality and thought it was hubris, since the only examples of ace people they did accept were literal gods. Narcissus was 16 when he died. A 16 year old who constantly gets sexually harassed has the right to be a little rude in rejecting people. Ameinias, for example, asked for the 16 year old's hand in marriage multiple times. If you want to say hounding a mid-pubescent child for sex is acceptable in any cultural context, then I'm going to view you the same way I view the ancient Greeks: as a pedophile.
Narcissus literally loved no one above himself. It wasn't asexuality it was hubris in the form of solipsism and narcissism - the reason why the condition is literally named after him.
And the Greeks cerainly DID understand asexuality, go and read Hippolytus.
Aromantic people are not sociopaths. It looks like you *think *you're being an ally or supportive, but you're actually being extremely offensive and abusive
Another detail about the myth you have to understand, in addition to all the sexual harassment of a child, is that Narcissus is a rape baby. He was born because Cephissus raped Liriope. That's his background for understanding the world of love. He exists because of an act of cruelty, which he is not old enough to distinguish from the sexual harassment he constantly suffers as a child because he was born pretty. Of course someone from that background, who has no feelings of love of his own, would end up resenting the very concept. I believe Narcissus was justified in telling Ameinias to kill himself, Ameinias was a pedophile and he was sexually abusing Narcissus with his harassment.
The thing it has to do with his asexuality is that he lacks the natural positive context for sex that comes with being allosexual. Most rape babies grow up, start having sexual thoughts, and are forced to come to an acceptance of sex. Narcissus has zero positive experience with sex. There's nothing to counter his association between sex and his mother's rape. That's explains why he's rude to people who sexually harass him. I thought that context might be helpful, since the other person in this thread is saying that he's evil for not loving anyone.
