The Trojans tend to be portrayed quite favorably by Homer, even to such a degree that many Greek and Roman literary critics speculated that Homer himself may have been Trojan. They are shown as a rational, civilized society rather than stereotypical "barbarians."
Paris is, to a degree, vain and motivated by erotic desires. He is a coward and selfish. When he was asked, as the most handsome man in the world, to choose to award the apple to one of the three goddesses, he chose Aphrodite, the goddess of love, over Athena, the goddess of wisdom, and Hera, the queen of the gods. His abduction of Helen could be considered irrational, letting lust overcome reason, but he was given permission to do so by a goddess, Aphrodite, and obeying the gods was considered reasonable.
Hector is in many ways the hero of the epic. He has a noble character and a strong sense of duty. He is a patriot and devoted to his family. His explanation of why he needed to fight is a model of rationality, balancing an understanding of the dangers involved with his sense of moral obligation.
Priam is a decent ruler, caring and benevolent. His pleading for the body of Hector balances reason with emotion.
