You can choose one thing to be the best at. Your title as the best will never be broken. However, you're only as skilled at it as you are now. Everyone else just gets worse. What do you choose?

 "Ugh, what the fuck?" John though as his alarm screamed at him from the beside table. He checked the clock, as a glowing 6:30 glared back at him.
 "Isn't it Saturday?" He thought, as the alarm continued it's wailing.
 "6:30 on a Saturday morning, what the hell?" He muttered to himself as he slapped the black plastic box in a feeble attempt at making it stop. He got up and checked his phone. An address was lit up on the screen, 2706 John Madden Drive, along with the time 8:30.
 "Oh shit, that's today?" John flung open the door to the bathroom and hopped in the shower. He quickly rinsed himself off, brushed his teeth, threw on one of the pairs of clothes that didn't smell like the bathroom of a third world county, and rushed to his car.
 "Fuck, I'm gonna be late." He said to himself as he fumbled to start the car, as an ominous 7:00 stared at him from the dashboard. The drive would usually take an hour, but traffic was unpredictable.
 Normally he wouldn't be too concerned, but this was important. He needed the money. That four-digit figure had been burned into his mind. "Two thousand dollars." The voice of the lady on the phone played over and over again in his head. "Two thousand dollars." He repeated, still not believing it.
 Normally, he would've be skeptical. Normally, he would've been nervous. Normally, he would've had a job. He had been fired two months prior to this event, and had been stalling with his landlord for weeks. He needed this money, and couldn't afford to turn down this opportunity, no matter how sketchy it sounded.
 As he was zoned-out in thought, in control of 2-ton hunk of careening metal, he had reached his destination. He pulled into the parking lot of a large white building. The most sterile looking thing he'd ever seen in his life. The building looked like freshly cleaned porcelain, and the reflection of the sun, just peeking over the edge of the horizon, blinded him as he tried to find a parking spot. Luckily, the parking lot was essentially empty. Probably because it was 8:20AM on a Saturday. "Oh shit, 8:20." He thought to himself as he started at the clock. As he was starting at it, the time ticked to 8:21, as if willing him to open the door and go inside. He gathered his thoughts, and opened the car door. As he was walking towards the spotless glass doors of the facility, he realized that even the concrete looked like it had been freshly power washed.
 He reached the doors, and grabbed the door handle, but it wouldn't budge. It didn't feel like it was locked. More like the handle was attached to a wall. It didn't move even a little. As he stepped back, confused, both doors opened to a lobby, with a single man dressed in a cliche white lab coat with a crisp white t-shirt, and white slacks.
 As soon as he entered the room, the doors closed behind him, returning to their immovable state.
 "Mr. John Simon, I presume? " Said the doctor in a calm, soothing voice.
 "Ya, I'm here for the -"
 "Oh, wonderful." The doctor replied, before John could finish his sentence. "If you'll just follow me."
 The doctor lead John down a hall, past door after door, of them all presumably locked, all of them identical. 
 "Here you are." Said the doctor, as he swiped a blank white card near the wall to the side of one of the doors. A green light, hidden behind a thin section of the wall, shone through, and a low him-like buzzing was heard as the door unlocked.
 "It's a pleasure to have you here." Said the doctor as he opened the door, and gestured for John to enter.
 As he walked through the doorway, into the complete darkness of the room, the door slammed shut behind him and he was left in silence. Suddenly, the room was flooded with light, blinding him. Add his eyes adjusted, he could see that the room was actually fairly small. Maybe 10' by 10', with a black panel the wall opposite the door, which had now been replaced by a blank wall.
 He approached the panel, and a female voice instructed him to place his hand flay in its center. He did add he was told, and a blue line moved up and down the screen, scanning his hand.
 "Welcome, Mr. Simon," Said the voice. "Please stand on the marked circle in the center of the room.
 He turned around to find a black circle had appeared on the floor in the center of the room. He stood in its center, and a loud pop was heard, followed by a ringing in his ears.
 As his hearing returned to normal, the voice thanked him and the door opened again.  He exited, and left through the same route which he had entered. He returned to his car, and drove home.
 As he laid down in his bed, he read the time on his alarm. 4:37PM.
 "What the fuck?" He thought. "I was only in there for a couple minutes."
 As he drifted off to sleep, he started to wonder why he couldn't remember the rest of the day, but he didn't care. He was too tired.

 When John awoke the next morning, he had 3 message on his phone. One was a bank statement, confirming the addition of $2000 to his account. The second was a news notification. The third was a text from on unknown number.
 He confirmed the bank statement, happy that he could eat diverging other than Ramen for once. He checked the news, and could hardly believe what he saw. The terror group ISIS had surrendered, along with countless other smaller organizations, and Putin had pulled out of Ukraine, apologized, and had begun paying reperations. On top of this, countless other news stories appeared in the next few hours that were similar, outlining a global shift to complete altruism.
 The final notification, the text, had been forgotten as he checked all known news outlets for the next hour. He returned to the text, and was shocked by what he saw.
 "Mr. Simon, we're the facility that you attended yesterday to assist us with an experiment," read the text, "we want to congratulate you on your part in one of the most groundbreaking events in the history of humanity. These news stories that you're seeing are because of us, and you. We succeeded in making you the most violent, evil man in the world, however, you have remained the same. The rest of the world had been altered to be more kind and generous that you."
 "Holy shit!" He yelled. He couldn't believe it. He was ecstatic, but it was brought to a halt when he realized that he was now, essentially, the worst human being in the world. He quickly realized, though, that it meant nothing to be the worst person in a completely kind world. This was fantastic!
 He turned on the TV to check the news again, but what he saw was...unnerving. A scene of anarchy and complete desolation in France. A small group of men had taken this opportunity to murder dozens of people. They had gunned down hundreds of people in the main tourist locations around Paris.
 Had...he caused this? Was all of this his fault? But, if he was the worst person, then who were these men? Was...was he...was he worse than men who killed thousands of people? How could this happen? What did it mean for him?

I'm sorry that it got shitty at the end, I'm being kinda rushed. If you want me to rewrite that shit I'll do it when I get home.
