Dead or stuck pixels are some of the things you have to deal with when buying a LCD monitor. Although rare some people (like the OP) will get them. The only suggestion I can make is to buy a "Dead Pixel Policy" if offered by the store. There is one, but I forogt the name since I don't buy stuff from them.
Intentionally damaging the panel is unethical. I'm guessing if you have the right equipment you can damage a pixel, but its probably cheaper to buy new monitor than it is to buy the equipment.
