In many gnostic schools, Jesus was not a sacrifice TO Yahweh/Yaldabaoth/the Demiurge, Jesus' sacrifice was to incarnate and show us the way out of the Demiurge's world. The Father is not the same thing as Yahweh, and echos of this show up even within the canonical gospels. 

>“Which of you fathers, if your son asks for a fish, will give him a snake instead?
Luke 11:11
>But the people grew impatient on the way; they spoke against God and against Moses, and said, 'Why have you brought us up out of Egypt to die in the desert There is no bread! There is no water! And we detest this miserable food!'
>Then the LORD sent venomous snakes among them; they bit the people and many Israelites died.
Numbers 21:4-6

Granted, this is not universal.
>(Jesus) found them sitting together practicing their piety. When he [came up to] his disciplessitting together praying over the bread, [he] laughed.
>The disciples said to him, 'Master, why are you laughing at [our] prayer? What have we done? [This] is what's right.'
>He answered and said to them, 'I'm not laughing at you. You're not doing this because you want to, but because through this your God [will be] praised.'
>They said, 'Master, you […] are the Son of our God!'
>Jesus said to them, 'How do [you] know me? Truly [I] say to you, no generation of the people among you will know me.'
...
>It's been said to the human generations, 'Look, God has accepted your sacrifice from the hands of priests,' that is, the minister of error. But the Lord who commands is the Lord over everything. On the last day, they'll be found guilty.'
Gospel of Judas

>God is a human-eater. Because of this, the human is [sacrificed] to him. Before the human was sacrificed, animals were sacrificed, because those to whom they were sacrificed weren't gods.
Gospel of Philip
