This is pretty much a schizopost, but I'd like to point out that Achilles has one scene in The Odyssey and he says that his heroic deeds weren't worth dying for because he's respected in Hades but he'd rather be alive as a serf on earth. He's a shade and is only able to communicate with Odysseus because Circe taught him how to do a sacrifice to communicate with the dead.
This is one of the most famous scenes in all of Western literature and you don't seem to know it at all, and posting a gif from a movie that both isn't great and that you also clearly didn't really understand is a lot to take in.
The Odyssey and The Iliad are complex works with a nuanced depiction of martial heroism.
