>>212183366 (OP)Denethor is neither a bad person nor a bad leader, in the book he makes sound decisions based on the information he has available
he just had to deal with Sauron, a supernaturally gifted manipulator, fucking with his mind for decades
It's where the movie goes completely wrong with his characterization, Denethor's fall was never meant to show his "weakness" it was meant to show Sauron's strength, in that he could bring low even a figure so strong as Denethor
