Nice.
Yeah, my view (and I stress this because people have differing views of alignment) is that "by any means necessary" cannot be a Good philosophy in D&D for the simple fact that including Evil means will eventually and inevitably corrupt the doer.
I'm not saying that an Evil act can never be done for Good, but almost anyone who lives their life that way will gradually lose sight of the truth of their actions, the justifications giving way over time to delusions.
Just look at fictional characters in the media. There are many, many examples of villains with good intentions; what makes them villains are the things they do to reach their vaunted goals.
