Ladification
A guy steps in to boss everyone around so they all end up failing, just because he wanted to be the cool one, and then everyone else goes, 'Man, I would've done that too,' and he doesn't get in trouble.
He took over the team just so we all got beaten up, and then said, 'I was protecting the team.'
He messed up the whole quiz so we all failed, and then said, 'I was doing this for the greater good.'
He took over the basketball game just to make sure we all lost, and then said, 'I was doing this for the team.'
