Why does lex luthor oppose superman in the movies?

In the DC Extended Universe, Lex Luthor is introduced in Batman v Superman: Dawn of Justice as the mastermind who pits Batman and Superman against each other. His primary objective is to eradicate Superman, whom he perceives as a perilous force that could dominate humanity. Luthor's actions are driven by a belief that eliminating such powerful beings will protect human autonomy and prevent potential tyrannical rule. This antagonistic stance is consistent across his brief appearances in Justice League and its director's cut, reinforcing his role as a villain determined to remove superpowered threats.
