Yes, free willers have people in hell paying a debt for sin that Christ already paid for once, and offered it to the Father, and was accepted by the Father as payment in full for each of those sins.
Humans don't make this offering "valid" by choosing or accepting. We are not in the stead of the Father, He accepted it, and all the sins that were intended to be paid for were, and they are the sins of His people; Matthew 1:21.
If a person paid your utility bills, but the utility company didn't let you know it had been paid, and demanded you pay it, that is dishonest and crooked yet that is the position many have God in in their unfamiliarity of the atonement and propitiation, yes, even the Gospel itself.
He knows what Christ did paid their debt, and sends them to hell anyway? That scenario is a disgrace and blasphemous to the finished work of Christ on the cross, His death, burial, and resurrection.
Some people need to spend some time in the word and get some sound doctrine; 2 Timothy 4:1ff.
