Homeless Danny Wilde, 43, killed Pamela Vardey, 75, after she gave him shelter. He "repaid her Christian charity with ruthless brutality", a judge said.
Wilde then set light to his victim's body at her home in Rotherham last September, Sheffield Crown Court heard.
Just days before he had been freed from a four-year jail term for burglary.
