Bad things would happen before the end
There would be no trials.
There would be no jails (massive riots would result in mass breakouts and/or entire prison populations murdered by guards to prevent them all escaping.)
There would be no legal repercussions for any criminal activity. Any possible spiritual or religious repercussions might prevent some, but not as many people as you'd might think.
Too many people would act on their fantasies, some of them very, very bad, because there would be no punishment. Hate your boss with a passion? Go ahead and kill him; you won't go to trial or a jail. In fact, attacking someone might get you shot so you wouldn't have to wait for the end. Fantasized about that cute girl in the apartment across the hall? Go ahead and rape her if she says no because you won't go to jail for it. It would get much, much uglier from there....
There would be people doing good things, of course, but they'd be overwhelmed in a tide of raging human beings angry at God, the universe, aliens, the government or whoever they'd blame for what is happening. They'd start taking out their rage on every person in sight.
Unfortunately, we've seen mob mentality and the breakdown of societies before throughout history, and it would be one hundred times worse in this case.
