Jesus "dying" wasn’t even really a sacrifice because he woke up

Jesus "dying" wasn’t even really a sacrifice because he woke up. Yes, he did feel the pain of death but the actual sacrifice of not "being here anymore" never happened. Death is supposed to be permanent. The sacrifice was "pathetic" in this case.

Another thing is that god set the whole "sacrifice system" up. He decided what our "reality"would be like and our laws of physics. He decided that sacrifice would be needed to clean away sins. Why would he decide that in the first place ? Why would he conclude that death is the way to "fix" a wrongdoing ? Killing that little lamb is not going to fix anything dude. You are still a piece of dookie.

This is my thought process of a few minutes so i most likely misunderstood a concept. I probably don’t understand sacrifice of have a misconception about it.

Is this a reasonable question ?
