Fair enough: Odysseus has a lot to be proud of. He's smart, strong, brave, and good-looking; he's married to a hot, loyal wife; and did we mention his pecs? Because he did. Yeah. He's kind of that guy. And a little bit of pride is just fine—it helps get your name out there and win you immortal fame, the super important Greek concept of kleos. But too much pride, and you're going to start ticking people off—or rather, the gods. And no matter how "godlike" Odysseus is, he's still a human. (Even if he doesn't look like one when he takes off his shirt.)
Odysseus is often justified in showing his pride because he has the goods—muscle, courage, and an honorable name—to back it up.
No character in the Odyssey can afford to have hubris, because it's always an offense against the gods.
