(LDS) What kind of payment can a murderer make to receive a pardon?

Related to this other question about whether murder is unforgivable according to the LDS Church. One of the answers to the question says that: > Murder is a very serious sin, and while it can't be forgiven it can be > pardoned. However the link in the word "pardoned" leads to a "page not found" message. This answer, however, does quote the following from D&C study guide in chapter 42: > The second most serious sin is to commit murder—that is, to willfully > shed innocent blood. Concerning this sin, the Lord has said: ‘Thou > shalt not kill; and he that kills shall not have forgiveness in this > world, nor in the world to come.’ (D&C 42:18.) **Thus this is an > unforgivable sin, which means that Jesus Christ cannot pay for (or > ‘atone for’ or ‘forgive’) the penalty demanded by the broken law. This > sin is a pardonable sin, however; that is, the sinner can eventually > make full payment himself, and be received into a state of pardon.** (Emphasis added.) So, murder is described as a sin that Jesus cannot atone for and yet, the individual himself can receive a pardon by making some form of a payment. --- My questions are: **1. What kind of "payment" can a murderer make to cover for murder?** **2. What are the differences, if any, between being thus pardoned and being forgiven by Jesus' atonement?**
