Buu (even Kid Buu) isn't truly evil for a handful of reasons.
Like I said above, there are certain gages you have consider for the culpability of a truly evil character.
A truly evil character needs to commit an act of malice with absolute intent to cause pain and destruction.
Even Kid Buu, was "too innocent" to really recognize the pain and suffering he was bringing upon people. To him, it was fun and games. It doesn't make him evil, it makes him completely misguided. In respects to Buu, he's more like a natural disaster then a true bad guy.
