James 2:10 says: "For whoever keeps the whole law and yet stumbles at just one point is guilty of breaking all of it" (NIV)
I’m not playing anyone’s game, but to answer your question, there are multiple explanations.
All it takes is one minor unforgiven sin to keep you out of heaven. In that case, they are all equally destructive (the same). Theres only one way for sin to be forgiven.
Another point is it is impossible to live by the law. Jesus' sacrifice replaced the law. Many of the laws are necessary as guidance, but they serve no purpose for salvation.
I don’t think we need to dive deeper to explain that there is a difference between stealing a piece of gum and child rape.
