Film theory: Ricky (Karen) doesn't actually redeem herself so she can go to heaven, but instead makes a deal with a demon so she can have weird powers or live longer or some shit... Tbh. She would, she's a cunt. So I'll do that to keep her in character, it's unrealistic that she'd be able to not curse Cyrus out for an entire lifetime. (Ladies and gentlemen, how to fail a character redemption plot.)
