I'm sorry if this is the wrong place to post this and sorry if it's a dumb question but I have a simple question: Is it legal in the American Justice System for someone to willingly take another person's punishment? e.g. If someone is convicted of murder, can they be released if, say, their brother says he will take the punishment deserved for the murderer? I'm not asking for speculation on the answer or debate on whether it's moral or just or not, I just want someone who knows what they are talking about to answer. Thanks!
