There was no hope from the start. You're just too naive to accept this fact. You're too delusional for your own good. He's dead.
Now there's no point in denying the inevitable, he's gone. Forever gone this time, you won't see him ever again. Those were the only thoughts in your head right now, as you stood in front of his grave, reading the same words over and over again.
"It was something this simple... Why couldn't be done sooner?"
Right. He could've been saved so easily, but no one cared back then, until it was too late. The fact that he had to burn and kill himself twice for his family to finally notice him is just sick...
Others would've said "He was someone's baby" but in this case, his 'someone' caused all of this. Maybe he's finally happy, maybe he finally found the peace after all these years. It was the only thought that could cheer you up slightly, make you smile and take another deep breath, making you forget about all the grief for a second. Maybe the part of him is still here, currently watching you, or even visiting his family sometimes
