Fujino took the easiest path possible and created an "NTR bully" with the most antagonistic features in contrast to Kirito. Kirito is in good physical shape - Inoda is fat, Kirito is kind and sympathetic - Inoda is an evil psychopath, Kirito is bad at sex - Inoda is good at sex, Kirito always respects women - Inoda is a rapist. Fujino chose the laziest and most cliched character possible. There are some games in which the "NTR bully" is not initially a bully, but develops his character traits precisely because of the influence of a cheating woman, but such games are rare.
And if you take all the character traits of Inoda together, then I don't understand how anyone can like this animal at all. It's like being a fan of Ted Bundy or Patrick Bateman from "American Psycho". I can officially declare it, and it won't even be just my opinion - everyone who likes Inoda, should be checked by a psychologist.(Yes, and you, Fujino, if you're reading this, go to a psychologist too

).
Even if you're also a fat loser and you see Inoda as your hero, it's better to think about what's wrong with you rather than looking for a role model where there obviously isn't one.
