First, your markup is broken. I can see the link-syntax, instead of the links. Also, the firs link is to an article by Phil Goetz, not Eliezer Yudkowsky.
Now about the actual content. I'm all for trying to use one's natural tendencies, instead of just trying to compensate for them. But I'm critical of the concrete examples you gave. What you are trying to do seems to be to motivate yourself through shame and guilt. And no one seems to be in favour of that. Some reasons why I think it's a bad idea:

If you never apply the negative image (the "enemy") to yourself, that might be a slightly different matter. Maybe the image of an alcoholic can help keep you sober if you never drink alcohol in the first place. But even then, you learn to be judgemental of people and, should you start drinking, you will have the before mentioned problems with punishment.
EDIT: corrected "disgress" to "transgress"
I think you're actually imagining this technique differently than I am. In my view, this actually removes pain and guilt. Instead of saying "oh, I was lazy". You say "oh no, the mustachioed villain Mr Lazy pants is trying to attack again" and don't internalize that guilt to you.
Likewise, you can imagine mr Lazy Pants attacking other people as well, which would cause you to be less judgemental of them, as they have to deal with the same evil villians that you do.
An often effective learning technique is the memory palace. The reason it works is because humans are simply better at remembering long routes than they are at memorizing long lists of abstract words, numbers etc. We have evolved in this fashion.
Apparently, humans are just inherently better at some things than at others.
In[this link](http://lesswrong.com/lw/31i/have_no_heroes_and_no_villains/), PhilGoetz argues that making heroes and villains out of people is a natural tendency. He views it as one of the habits that can be de-programmed, but requires effort - "a conscious effort to shatter the good guy, bad guy narrative".
But can we do better than simply de-program this tendency? Can we put it to use the way, the memory palace has been subverted to our own end?
[Anthropomorphism](https://en.wikipedia.org/wiki/Anthropomorphism) to the rescue.
Make that short-tempered habit of yours, the alcoholic wife-beater that you loath. Make your habit of procrastination, the lazy employee in the office who never gets things done and gets his whole team into trouble. Make your deepest insecurities, the most despicable version of Peter Pettigrew that you have come across.
See if it works. Let me know in the comments section.
