Is naxalism justified?

I am a baby leftist and I find myself sort of sympathyzing with the naxal moment due to the reasons that led to the movement. But I find myself feeling difficult when I hear about the attacks targeted at normal citizens (although rare) and sometimes cops and crpf officials. Is it the government that makes them the scapegoat? And, are individual naxalites groups and movements to be treated as different and not at all correlated?

I also heard that the tribals are troubled with the naxals and often times naxalites execute the tribals who are proved to be counter revolutionary, the definition of which can be different according to the individual.
