Goku tried his best to think of something to do but before he could even begin to try to think of a plan with any chance of working he was stopped.
"Do not try to interfere; this is how it should be. Saving me will also save piccolo… and I will not let that happen!" Kami shouted the last part so as to make sure he was understood. He they probably couldn't do anything to save him and Piccolo, he was too far gone for anything to be done in time, but he didn't want to risk it, he had gone through too much to give up now just so he can prolong his own life.
The only problem with his death was the loss of the dragon balls. He didn't really consider that a loss himself, he had originally made them for the Earthlings with the hope it would encourage heroes to do great acts and improve the lives of many.
But that was not the case.
They had been being misused since they were discovered. People only wanted selfish wishes, immortality, increases in power, world domination. It made his sick. Those wishes helped no one but the wish maker; they didn't deserve to be fulfilled but the dragon always granted wishes indiscriminately even if he wouldn't grant them if he could decide.
The thing that had upset him the most wasn't this though. He could handle the selfish wishes if they were balanced out by wishes for good things. But they weren't, wishes to help others were a rarity. That's what bothered him, the dragon balls were being used for evil instead of good, their power was being abused and he hated it.
He had been thinking about deactivating them himself recently, he had seen how the red ribbon army had almost gathered them all themselves. If they had had them who knew what they would be used for, he didn't like to think of it.
The worst part was that he wasn't even the one to prevent such an atrocity taking place, it was the Saiyans. They would soon be far stronger than he ever was, so, why would the Earth need him. They would do just fine protecting it in his absence like they had today, and they would only keep getting stronger.
He could sense that they had only accessed a tiny fraction of their full potential. They were capable of things that he couldn't even imagine, all he would do from here on out was get in their way.
He was slightly concerned about who would take over as guardian of Earth. He had initially though that the youngest of the Saiyan, the one they called Kakarot, who called himself Goku, would be a good man for the position.
He was pure of heart after all, which is a very rare quality amongst the population of Earth. But he soon realized that he would not be a good replacement. The guardian of Earth needs to be wise, something which he clearly was not. He may succeed in beating up any threat to the planet but he wouldn't be able to make good overall decisions about the Earth.
He then considered Bardock, the eldest and clearly the wisest of the Saiyans. He clearly would be more than strong enough to protect the Earth. He could properly make good decision about what should be done in regards to treating the Earth issues, he had done pretty well with piccolo after all, although he did underestimate his new power initially he recover and though of a new plan within seconds.
Then again he was not pure of heart. He clearly would be more attracted to the power given to the holder of the position than the actual doing of it. He knew that wasn't good, after all that why he had been rejected for the position all those years ago even after he defeated Garlic.
He shot down Vegeta as a candidate for the same reason; he was far from pure of heart. Although he wasn't as far as Bardock, Bardock had purged entire planets killing millions in the process. Vegeta had only killed him, and he didn't seem to have wanted to, he clearly just wanted Piccolo dead.
He knew Mr Popo would be crushed. Mr Popo had always been very fond of him; he knew this because he was so high in the pecking order compared to other Mr Popo would meet. Mr Popo had been around for a long time, he was with Kami only knows how many guardians before Kami.
Kami knew Mr Popo would find him an appropriate replacement when he was gone, he let this though comfort him as he blacked out, preparing himself for the afterlife as he did so.
In the darkness he suddenly saw a pair of huge round eyes looking at him, they seemed to be moving away as soon he was a red curve that turned into a mouth. He soon realized that this was Mr Popo; he assumed he must be imagining it as a result of something strange happening in his brain during death.
He was shocked when Mr Popo started laughing, as if he was finding his death amusing. The laugh made his skin crawl when combined with the completely at ease features on Mr Popo's face but he didn't have the strength to question it.
He couldn't be sure but he assumed that he would pass within seconds; he based this off of human experiences he had witnessed of course so he wouldn't be sure. After all he was far from human, even if he was raised around them for so long, and couldn't assume that he would have the same death.
He also wasn't dying in a way that anyone that he knew of had died before. He truly had no idea what to expect. Would he merge with Piccolo as a result of his death? Maybe he would end up in hell because of what Piccolo, a part of him, had done during his life. He couldn't be sure, but, surprisingly, he found he didn't care at all.
It was over and that's all he cared about.
The self-proclaimed demon king had been killed and could never harm anyone again. Many of the people of Earth didn't even know what he had caused. They had rebuilt everything, so now he was gone everything would be fine.
So with that though he let the darkness, which no longer held the image of Mr Popo's smiling face, consume him and bring him to the other side peacefully. He had no intention to try to hold onto his life.
Unfortunately King Piccolo didn't think the same way.
