jesus and sacrifice

The whole thing is just very strange once you actually start to think about it. So "sins" (btw what even is this concept, some sort of supernatural criminal legal system? who decides what is a "sin" and why does this authority have jurisdiction over me when i don't even get a vote? what if i just decide to go all "sovereign citizen" instead?) can be wiped clean with (pseudo-)human sacrifice, and not only does it indiscriminately apply to all past "sins" but somehow all future ones?

Doesn't make much sense to me, but what do i know, i'm no expert in taking fantasy literature way too seriously theologian.

Also, I never asked Jesus to do that for me, that's kind of presumptuous of him to just assume i'd want that. It's like someone saying "well i just did this thing for you completely unprompted that you never asked for nor wanted, but because it's such a "nice", selfless thing i did, you now owe me eternal gratitude". Sounds a bit narcissistic tbh, sounds like incel behavior. It's like, nah dog, you getting your ass crucified, that's on you, don't try and make it my problem.

you have the supernatural ability to create, destroy, or do anything you want, but are too lazy to fix the most obvious of plotholes.

While true, he did get tortured.

"Jesus suffered for your sins" would be more internally consistent to their mythology.

Jesus played hooky for our sins.

It probably feels like a cop-out, but one could hypothetically respond by saying that the temporary loss of the son sufficed in the Almighty's eyes. He could have drowned everybody on Earth, much like in the book of Genesis, but in His mercy He toned down the penalty to one temporary sacrifice, which has impressed millions. He could have made a sacrifice of a more permanent nature (as a few Christians believe), but that would have complicated His benevolence.

Not a perfect explanation by any means, but I am no Christian, so I am not the best source to consult on this. My own view of the matter is more complicated...

The thing that gets me about the religious stuff I was taught (catholic stuff) is like the whole thing with "original sin." I'm supposed to be tied up in responsibility for a decision that some ancestor made millennia ago. Holding children responsible for the sins of their parents is some real ethnic-cleansing-justifying mindset. Not to mention, the whole story of the "sin" in the first place; in the most charitable interpretation I can think of, they were purposefully tempted and fell to temptation and God was like, yeah, that's it, you're done. And then it took a long time and Jesus getting himself tortured to death in order for God to reconsider his stonewalling of humanity. But Jesus is also a part of God, according to catholicism, IIRC; the whole three persons in one thing. So in a way, it seems the catholic God is like those people who can't empathize with suffering until similar happens to them, then they finally get it. Though considering this is what I was taught in the western empire and considering (in my understanding) catholicism's historical ties to such levers of power at least in more recent history, I guess it shouldn't be a surprise if God comes out looking like a sort of Scrooge character who is out of touch with the suffering he is causing and can be moved to charity (not even reform, much less overthrow) only if he suffers first.
