Well, Lex Luthor started out in a rather difficult situation. In his origin story, he was from a not - so - well - off family in a tough neighborhood. However, his genius was evident from a young age. He managed to build an empire through his wits and business acumen. But his encounter with Superman, a being with god - like powers, made him feel inferior. This sense of inferiority and his overarching ambition led him down the path of villainy. He began devising plans to take down Superman, believing that without Superman, he could be the most powerful and respected figure in the world.
Lex Luthor's age isn't fixed in the comics. It can change based on the creative direction of the writers and the era of the story. Generally, he's portrayed as an adult in his prime, often in his late 30s to 50s.
One key element is his intelligence. Lex is extremely smart from a young age, which helps him build his business empire. Another is his sense of envy. When Superman shows up, Lex is envious of the attention and power Superman has. Also, his upbringing in a not - so - privileged background might have contributed to his desire for power and recognition.
It can be disrespectful to the original source material and the intentions of the creators. The character of Lex Luthor has complex traits that should be explored in more meaningful ways.
Well, Lex Luthor's death varies depending on the comic storyline. Sometimes it's due to his own schemes backfiring, other times it's at the hands of a powerful foe.
