Killing Gandhi
You have the gun out and drawn, and after so much time of thinking people are starting to just barely notice you. You have to act now. You start to pull the trigger over and over again, being careful to not hit Gandhi, and as you do, you see bodies start to fall to the floor. You start to feel ashamed of what you are doing before you even stop doing it. After a little while you put the gun away, and run. You didn't go far before the police caught you. While you are sitting in a jail cell you see on TV that not only did you end the lives of tens of people. The count included Gandhi. A couple days after the incident Gandhi died of starvation and depression. He couldn't handle it, and now you have that burden for the rest of your life. One that will linger with you constantly, and you have to remember something terrible that you did, forever.
