Was Martha a good or a bad idea

Or a longer option when he sees Batman is winning:
Superman drops to his knees. "You are going to do this, and apparently I can't stop you. But after it's done, make me a promise. Lex Luthor is holding a woman hostage. She is a good and innocent woman and if you don't hurry up and kill me, he will murder her. Her name is Martha, tell her I love her and I tried."


ANYTHING but "YOU'RE LETTING HIM KILL MARTHA!"
