Actor Keira Knightley, a self-confessed atheist, says she is desperate to be Catholic because she would “just get to ask for forgiveness”. “It sounds much better than having to live with guilt. It’s absolutely extraordinary. If only I wasn’t an atheist, I could get away with anything,” thesun.co.uk quoted the Pirates of the Caribbean actor as saying. “You’d just ask for forgiveness and then you’d be forgiven,” added the 27-year-old, who will be next seen in Anna Karenina.
