All sin has a penalty, just as all crimes should. God did not have to sacrifice Jesus (and this is where some Christians really need to read and take into account all of Scripture) Jesus, who is God come in the flesh, chose to pay the penalty for our sin Himself. As He said, John 10: 11 - 18
11 “I am the good shepherd; the good shepherd lays down His life for the sheep. 12 He who is a hired hand, and not a shepherd, who is not the owner of the sheep, sees the wolf coming, and leaves the sheep and flees; and the wolf snatches them and scatters the flock. 13 He flees because he is a hired hand and does not care about the sheep. 14 I am the good shepherd, and I know My own, and My own know Me, 15 just as the Father knows Me and I know the Father; and I lay down My life for the sheep. 16 And I have other sheep that are not of this fold; I must bring them also, and they will listen to My voice; and they will become one flock, with one shepherd. 17 For this reason the Father loves Me, because I lay down My life so that I may take it back. 18 No one has taken it away from Me, but I lay it down on My own. I have authority to lay it down, and I have authority to take it back. This commandment I received from My Father.”
