Save the day to destory the world!
How could you destroy the world by saving the day?
Your goal is to go back to any point in space time and do only good deeds that would most likely cause incredible harm eventually as a direct or indirect result.
For example.
I've chosen to go back and convince the Kryptonians that Jor-El is right about the planet's possible destruction and have helped them to save it all. Then I show up knock the gun outta Joe Chill's hand before he was able to attack Tomas and Martha Wayne. I transport Bruce Banner and Rick Jones from the site of the gamma bomb blast. Make sure uncle Ben's killer was caught and arrested just hours before he'd even went to the Parker's residence. Pulled Barry Allen out of the way of the chemicals and lighting bolt. And added the extra shielding needed for Reed Richard's space ship to be protected against cosmic radiation.
So basically what are the best deeds that could have been done to have led to the worst conincidences?
