[Star Wars] Why do so many Jedi turn to Sith masters when they know that, by definition, it will only lead to misery and death?

The Sith practice a brutal system where the master *must* be killed by the apprentice or the apprentice will be killed by their master or someone else, all for the greater goal of creating an individual who will have more power than their master to pass to their apprentice.

The Sith doctrine emphasizes passion for power, most notably wrath, hate, depression, and overall misery.

Why would anyone other than those desperate for power (Such as Anakin trying to save Padme or Darth Nihilus trying to be immortal) choose to follow Sith Teachings? 

If a Jedi was stifling under the Jedi Order, why would they join the Sith when they could just use their powers to be an awesome bouncer on Nar Shadaa and party every night, or a similar rebellious action to takeout their frustrations with the order?

Because you don't see the hook until it's already in you.  
Jedi don't just up and decide to turn Sith.  It's a path of deception and seduction that leads you towards it one tiny, apparently reversible, step at a time.  Always just a little farther telling yourself you just need to learn this one thing and then you can turn back until you find you've actually passed the point of no return long ago, and you're so beholden to your master that the only way out is to become more powerful and kill him.
