I'd encourage anybody interested in creating a self-styled "Odysseus" to take influence from the ancient myths regarding him as they provide the names of his friends, rivals, enemies, as well as MUCH potential fodder for story arcs.
The wiki says of Odysseus, " He is most famous for his nostos, or "homecoming", which took him ten eventful years "
It's fate, then? Isn't it? Density! -note- I think it's not just a literal homecoming, it also seems to be meant as a psychological recovery from the horrors of war and a return to normal, civilian life.
When Helen is abducted, Menelaus calls upon the other suitors to honour their oaths and help him to retrieve her, an attempt that leads to the Trojan War. Odysseus tries to avoid it by feigning lunacy, as an oracle had prophesied a long-delayed return home for him if he went. He hooks a donkey and an ox to his plow (as they have different stride lengths, hindering the efficiency of the plow) and (some modern sources add) starts sowing his fields with salt. Palamedes, at the behest of Menelaus' brother Agamemnon, seeks to disprove Odysseus' madness and places Telemachus, Odysseus' infant son, in front of the plow. Odysseus veers the plow away from his son, thus exposing his stratagem.[24] Odysseus holds a grudge against Palamedes during the war for dragging him away from his home.
Odysseus and other envoys of Agamemnon travel to Scyros to recruit Achilles because of a prophecy that Troy could not be taken without him. By most accounts, Thetis, Achilles' mother, disguises the youth as a woman to hide him from the recruiters because an oracle had predicted that Achilles would either live a long uneventful life or achieve everlasting glory while dying young. Odysseus cleverly discovers which among the women before him is Achilles when the youth is the only one of them to show interest in examining the weapons hidden among an array of adornment gifts for the daughters of their host. Odysseus arranges further for the sounding of a battle horn, which prompts Achilles to clutch a weapon and show his trained disposition. With his disguise foiled, he is exposed and joins Agamemnon's call to arms among the Hellenes.[25]
As you can see, Oracles provide MUCH motivation for the crackpot adventures had by the ancient greek mythological characters. The two great motivations for humans are greed and fear - Oracles provide the potential for both. Oracle this, Oracle that, warnings and portents galore and all without a SHRED of EVIDENCE! Perfect rationale for even the most heinous of crimes!
