(Video game) aita for moving a dea body during a moment that puts everyone's life's at risk?

I (19M) got my memory wiped and thought I was still in my high school days, so I thought I was 16. I was trapped in my school, and the only way to leave was to murder and get away. I had only ever seen one trial, so when I found another dead body in the boys’ locker room, I moved the body to the girls’ bathroom, swapped the posters, and set it up like a serial killer who may or may not be trapped in the school with us,also i hanged up the dead body with a fucking lamp power cord, then during the trial I revealed i fake dit to make things more interesting
