Of course, the entire concept of this thread leads to nothing more than individual opinion, but here's mine:
"The ends are as important as the means and Evil is never justified."
Oh, sure, people may convince themselves that an act of Evil is "neccessary", but that does not make its employment "justified".
To provide a sampling to help people understand where I'm coming from and where I'm going with this, I will use it in terms of capital-G "Good" and capital-E "Evil":
1) Using Good means to achieve a Good end is Good.
2) Using Evil means to achieve an Evil end is Evil.
3) Using Evil means to achieve a Good end is Evil.
4) Using Good means to achieve an Evil end is Evil.
Again, that's my opinion. Take it for what you will and, by all means, feel free to ask questions.
