Re: Not exclusive.
getting a bunch of people killed for acting within their own framework of morals and beliefs in the name of his own morals and beliefs
Everyone "act[s] within their own framework of morals and beliefs", if they consider their actions at all. That's what morality entails: considering whether an action is good.1
Consequently, when two factions are opposed, there must be a conflict between their "morals and beliefs", except in the unlikely event that one or both factions is acting in an entirely unconsidered manner. Clearly that's not the case here, since both sides2 are presenting arguments justifying their positions.
Leaving aside the question of whether indeed anyone is "getting ... killed" as a direct result of Snowden's actions, the issue of conflicting "morals and beliefs" does not have any bearing on the morality (or, for that matter, ethical appropriateness) of Snowden's actions.
1Whether an unconsidered action can be moral or immoral is a matter of philosophical debate; Kant, for example, argued that morality only attaches when the actor is cognizant of the good or evil in an action.
2Really "all sides", since there are many positions on the matter.
