For religious people, sin is a big issue… mostly our own sin, but also the sins of others, which we somehow consider to be our business. Jesus died to pay the penalty for all of the sins of all people, but we still wage war against our broken hearts and our broken relationships.
I understand your concern, as many Christians have grown up with the idea that burial is the option that God prefers. They see some connection between burial and resurrection. Of course, that doesn't quite make sense.
