Orestes was the son of Agamemnon and Clytemnestra in Greek mythology, who was hunted by the Erinyes after he killed his own mother. No one could have guess what Orestes’ proper course of action would have been, if he was alive today.
Why? He probably would have done something not good with his knowledge, he could have suffered from something, he could of gotten bored of living too long, he might of had a different train of thought if he was born in these modern days, the world would be a different place (for someone or some people or maybe the the entire world) if he was here now. Nobody here on earth could guess what would have been Orestes’ proper course of action, had he been alive today, or a 1000 years ago, or how many years ago or from now, he might simply would of become/became a different person.
