^Perhaps. Good intentions often produce bad results, especially if the wrong method is employed to pursue them. It's just important to understand that nations rarely consider themselves "evil." They're usually trying to do what they think is best for their own people, but different nations have conflicting priorities and worldviews and that's where conflict comes from. Simplifying it to good vs. evil is usually just propaganda that gets in the way of understanding the real issues and causes. True, a lot of fiction does dumb down politics to good vs. evil, but Star Trek
has rarely done so. Even the Klingons, who were generally pretty irredeemable in TOS, were shown more sympathetically in "Day of the Dove," and it was stated in their first appearance that they would one day be friends with the Federation.
