Do what you want for your happiness, but you need to be ready to justify it, or fight for it. Sometimes doing what you think is good will be considered as evil, and will pose a significant obstacle to your pursuit of happiness. It's an interesting thought that "I think people should do what makes them happy, I don't care if someone calls it good or evil." and one I would like to support. But that does not mean it is one that is practical in the real world. I generally have highly theoretical ideas, and ones that would likely not be possible. I truly do believe that you should do whatever makes you happy, consequences be damned. However, that really isn't possible in the real world.
