>Murderers in the Kingdom are executed humanely with poison and then have their remains used as tree fertilizer

What would be the reasoning behind this custom?

Poison is not the most humane death. It's just looks that way because no blood is spilled.

He might mean the poison used on Socrates, it was kind of painless. Perhaps.

You aren't taken by the birds or by smoke and therefore taken to judgement.

You are taken by the Earth and are therefore reincarnated. Maybe you won't fuck up so bad next time around.

There are worse ways to go than milm of the poppy overdose.

The tree is of a specific type to let all who see it know that a failure is buried here. Point and laugh.

Only because they screwed up and used wrong plant. It probably was still incredibly painful in the last moments when paralysis reached heart and lungs, but there was no way for Socrates to articulate it.

They hate trees and wish to poison them

Just copy paste story of Cain and Abel till the curse part and say that he was beaten by snake (who may as well talk him into idea why not). And then Adam found him and buried under some tree. Kingdom belives that it is the same tree.

A famous and beloved ruler went nuts an murdered someone, so s/he was given a respectful death, and the tradition continued in their honor.

Cultivation of murderous treant army.

Ancient king was a tyrant who wanted his garden watered with the blood of his enemies, executed in the slowest, most torturous method. Because it gave a brutal message to any dissenters, many noble copied this style of execution. As generations went on, future nobles and kings toned down the traditions of old, but still keep the general idea, because anyone too far from the norm often found himself 6 feet under a tree.
