NEW DELHI — In the months after the death of a young woman who was brutalized and gang-raped on a moving bus in New Delhi in 2012, thousands of politicians, activists and ordinary citizens crowded India’s airwaves and its public spaces to say their piece about the crime.

But there was no comment from the six slight, ordinary-looking men accused of her murder. Whisked in and out of the courtroom past shouting crowds of journalists, they listened impassively to testimony and offered monosyllabic answers on the stand. Courtroom guards said they hummed Bollywood tunes under their breath. Their opinions were anyone’s guess.

Now, one of the men on death row for the crime, Mukesh Singh, has told a British filmmaker that the young woman invited the rape because she was out too late at night and that she would have lived if she had submitted to the assault.

“You can’t clap with one hand,” said Mr. Singh, who was convicted of rape and murder, though he denied taking part in the assault. “It takes two hands. A decent girl won’t roam around at 9 o’clock at night. A girl is far more responsible for rape than a boy. Boy and girl are not equal. Housework and housekeeping is for girls, not roaming in discos and bars at night doing wrong things, wearing wrong clothes. About 20 percent of girls are good.”
