I just gave you an answer. To meaningfully "sacrifice" something, one has to actually LOSE something. Jesus supposedly suffered, sure, but after three days of suffering they were then returned to life before ascending to heaven and becoming the literally most powerful being in existence and got to be continually praised by billions of people for thousands of years. In other words, Jesus ended up with MORE, not LESS. Nothing was sacrificed. Especially when you remember that the need for a sacrifice to begin with was created by Jesus in the fist place. They literally didn't have to die, suffer or do anything in order to produce the exact same result. It's like me hiring a hit-man to kill you, and then making a "sacrifice" by calling off the hit man and being endlessly praised for it. It's absurd.
