The best "negative motivation" movies (or books, etc.)? Requiem for a Dream is the best negative motivation movie I ever seen. This movie really helped me.

And recently I started to notice that negative motivation is the only type of motivation that really helps me. 

What other [really good] negative motivation movies do you know? Or may be books, something else?

Maybe this question is off-topic here. But I really need to know other negative motivation movies.

Sorry for my English
Goodfellas and the Wolf on Wall Street both leave the watcher contemplating the results of the actors bad behaviour. The two movies are highly related; one is about the mob and the other about the market place. 

Learning from bad behaviour and seeing it fail is method used in moral storytelling called conditioning. Its an old idea that goes all the way back to ancient animal training but was first formally studied by Pavlov. Negative reinforcement causes people to lose an appetite for evil by seeing the devastating outcomes and punishment so that those behaviours are associated with pain and loss to cause avoidance.
