Smallville’s third season is widely regarded by fans and critics as the moment the show shed its "freak of the week" skin and evolved into a complex, Shakespearean Greek tragedy. If Season 1 was about discovery and Season 2 was about origin, Season 3 is about the consequences of destiny.
John Glover has always played Lionel with charm, but in Season 3, the nuance disappears. This is Lionel at his most monstrous. He murders his own parents in a flashback. He has his son committed. He tries to have Jonathan Kent killed. Most shockingly, in the episode "Memoria," we learn the truth: Lex’s obsession with his dead brother Julian is misplaced. Lionel’s wife, Lillian, died giving birth to a stillborn Julian. To "fix" her depression, Lionel secretly adopted another baby (the actual Julian) and then, when Lillian rejected the fraud, Lionel had the infant killed. He killed a baby. This revelation is the final nail in the coffin for any redemption for Lionel. He is the devil of Smallville , and watching Lex finally imprison him in the finale ( "Covenant" ) is one of the most satisfying moments in television history. smallville season 3
