So having care in the process of burning the body and honoring the cremains isn't treating the body with the honor due but putting someone in a pine box and burying them in the dirt to be eaten by worms and "leach corpse juice into a water table" is treating the body with the honor due?
Because burning a body is inherently disgusting. Try it with a small animal, see how it is. Commiting someone to the earth is far less awful, far more natural, and just generally better.
In concept, cremation is lovely. In practice, you need a bone grinder, a cremation chamber that requires you to break the femurs of the dearly departed to fit them inside, and massive filtration to prevent the entire area from smelling of burnt corpse. Burial requires a box.
And rotting in a box "leaking corpse juice" isn't disgusting. Try it with a small animal, see how it is.
Honestly though, I can't really try it with a small animal as I don't have a cremation retort capable of reaching the ~1,500-2,000F that are common on actual cremation retorts. I don't know what kind of oven you rock in your kitchen but mine tops out ~500F.
How is burying more honorable than cremation?
