I disagree. Historically, the distinction between freedom fighter of just cause and terrorist is the notion of what is considered "too far" to achieve a certain goal. In the series, Karli was introduced via the Flag Smashers' message (leading some viewers to see her--by association--as a sympathetic figure), but in time, Karli--as an individual--was revealed to operate on a level apart from the other Flag Smashers, having no "too far" which was questioned by her associate. For a real world example, in the early days of the Black Liberation Army, there were some divisions about methods and intent; some wanted to strike blows against institutions such as government buildings & rob banks (and/or armored trucks delivering money), while others were Hell-bent on assassinating police officers, as they saw fighting the system and "sending a message" possible only through murder (against agents of the state). Karli represented the latter mindset, as she was impatient, with her fluid modification of Flag Smasher doctrine escalating to the "all or nothing" plots embracing the killing of innocent people to send what she believed to be a message forcing her enemies to capitulate.
