Sick and twisted

Sin

"I.. I cannot go on, Scoob."
"SHAGGY! It's-a me... MARIO. Scoob has been-a dead for fourteen-a years now! You need-a snap out of it!"

Mario attempts to lift the skeleton of a man up, they still have a long way to go. Shaggy, however, burrows his face deeper into the gravel.  The atmosphere mimics Shaggy's hopelessness, cloudy and smog-ridden. Suddenly, Mario notices the sound of a low, rumbling engine.
"Shaggy... get-a up!" he whispers.
"Like, no Mariooo, I only find comfort with my face in the bosom of Mother Earth."
"B-but shaggy! There's-a tank... the Chinese-a Communist Party is-a gonna run us down!!"

With those words, Shaggy arose. You see, the Chinese Communist Party took the life of his one and only friend, Scoob. Mario looked up at the lanky, bitter husk of a man. It appeared that Shaggy's grief took the form of a deep-seated lust for revenge.
Mario, in his wisdom, pleaded for Shaggy to hold himself back, but it was far too late. Shaggy powered his mega-punch, growling and staring down the encroaching tank.
"N-NO SHAGGY!" Mario yelled.

It was far too late.

With the blast of a thousand choirs of seahorse cyborgs, Shaggy shredded through the tank as if it were a already-torn piece of paper.

When he turned around, the hatred in his eyes vanished. His knees buckled, and he could not believe what lay before him.

"Ruh Roh, rhaggy..." a weak and somber voice gasped.

Scoob laid in the rubble of the war machine, missing the lower half of his body. His breaths did nothing to staunch the flow of blood, and his grasping for his legs could not be reattached.

Shaggy rushed to the side of his bestest friend, who was now losing the little light left in his eyes. "S-SCOOB!! YOU WERE, LIKE, DEAD DUDE!" Shaggy sobbed, Scooby shook his head. "Nuh-uh... Rart Rof Rommunist Regime, raked reath, rI'm rorry, Rhaggy..." the dog coughed, spitting blood as he confessed.

Shaggy, in disbelief, began to play that one funeral song on his trumpet. His sorrows cut deep, and the revenge he sought now gave way to a void in his soul. Scooby passed peacefully in the arms of his killer at 4 PM EST. His funeral will be held on Sunday, at 3 AM EST. Shaggy will lead the procession, and give a loving speech about his fallen comrade, may he Rest In Peace in the bosom of Mother Earth.

Mario led a life of crime afterwards, starting a pasta cartel which delivered good via pigeons. He is now a linguini addict and is serving time in Alcatraz, off the coast of Miami, 3 PM EST.
