Yes. Most major villains in long-running comic series's experience a lot of flip-flopping and revisions that make their true natures really hard to pin down (especially in X-Men's case--I mean, how many times has Magneto switched sides again?). However, Sinister is one of those rare villains who not only stays as horrible as when he started, but gets worse over time as well, with hundreds of deaths and brutal experiments performed on others for the sake of his twisted "research", as well as the personal strife that he's inflicted on the lives of the X-Men on top of that.
