* AlternateCharacterInterpretation: The entire point of the series. Lex Luthor presents his side of the conflict between him and Superman. The point of the series is that, Lex's argument aside, he's a monster.
** Additionally, do the final words [[spoiler: "I am a man, I hope." mean that Lex thinks his hope makes him a man? Or do they mean that in the face of all the evil he has done Lex is clinging to hope that he is still a man?]] Both interpretations are valid.
** The story has produced some differing interpretations over exactly how responsible Luthor was for everything that happened [[spoiler: including the destruction of the jewelers/daycare center that drives the final act of the plot]]. Less responsibility would make Luthor a WellIntentionedExtremist who perhaps tips over into KnightTemplar territory, while more would make him a self-deluding mass-murdering lunatic. The story itself is somewhat ambiguous on several points, but suggests that the sheer depth of Luthor's Machiavellian personality makes it highly unlikely that he was completely unaware of what was going to happen even if he wasn't responsible.
* DracoInLeatherPants: The fact that the story's understanding of (although it doesn't actually agree with) Luthor's worldview, coupled with some ambiguity over exactly ''how'' responsible he was for everything, has led to this being applied to Luthor from some quarters.
* MagnificentBastard: Lex.
* MisaimedFandom: Luthor has persuaded some people -- both in-universe and in real life -- that Superman is a threat with his arguments. Also, that he's correct in his view that humanity must always fear aliens (by which he means [[{{Superman}} this alien]]- Lex has always had less of a problem with actually malevolent aliens, like {{Brainiac}}, even teaming up with them at many points). The point of the story is that Lex Luthor, a human being, is about as big an enemy to humanity as humanly possible.
* MoralEventHorizon: Lex's 'great contribution to humanity', his charity towards his janitor's son, and everything else -- ends in tears. Lex still feels guilt, though -- or, at least, he ''tells'' us he feels guilt.
* StrawmanHasAPoint: Much of what Lex says (That humanity shouldn't place too much faith in aliens who could easily turn against them) makes sense and is very convincing. So much so that it's easy to forget what a monster Lex is. [[FridgeBrilliance Just like characters in the story and Lex himself do]].
* {{Squick}}: This can be the reaction upon learning that [[spoiler: Luthor essentially had sex with a robot]], with further Squick possible upon realizing that [[spoiler: Luthor's such a messed-up control freak that the only real relationship he can have is with a woman he completely designs and builds himself.]]
