I'd probably kill my enemies and steal a car and run over people for no reason and break into a gun store and go loose with 12 gauge shots guns and possible If i'm not dead yet either steal a plane of a tank and crash it into a military base or the stock market place with lots of crazy people. My plan hasn't changed since I was 9
Wow ... you really missed the boat on this one ...
If you knew that you were the last sentient being to ever live, what would you do? Celebrate? Cry? Go on a rampage? With nobody to stop you, the world would be yours for the taking.
So you would go around killing people, that don't exist, with 12 gauge shotguns.
Yup ... you'll never pass the psych test.
