Can we call it Collective Action

I come from Gaya(Bihar) the holly land of Gautam Buddha, and the kind of hatred and killings it has witnessed in the last decade one cant even think of on the hands of MCC and Ranvir Sena( sena formed by Forward class to protect themselves from the atrocities of MCC) .
MCC was formed on the ideology of social justice for socially and/or economically downtrodden people. In the 90s we witnessed altogether a new party which had forgotten its ideology and preferred resorting to bloodshed/killings of innocents but for the cast they belonged to.it started targeting a particular cast. What they used to do is - initially they set their targets(village) after quite deliberation and invade the village so chosen in large numbers using different tactics.sometimes it was in the form of Hallabol and on other occasions they resorted to Guerrilla war . they used to capture that village by using bullet power and then they tie people,ranging between 40-85 , depending on village youth strength with rope and lay them all on the ground and then after shouting for MCC they start the brutal game of mass killing(s). For killing ,they use Hasiya ,a knife like tool, and after half cutting their throats they move on to the next and so on and so forth .in some sense men and corks are same to them as far as the end (death) is concerned.
All this created havoc in people coming from same class/cast and they decided to form their own sena and this led to the formation of Ranvir Sena(RS) . As it was formed by so called afluent people so it was equally/better equipped in comparison to MCC. RS started working on 5 for 1 strategy meaning if MCC killed 1 person they would kill 5 persons of Schedule casts. they used to invade sc villages and stared firing bullets and thus who so ever including women and children came in the range opf bullets was killed. after some 10-20 such attacks and counter attacks MCC was forced to give up killing by their members.
What is important here to note is that whether MCC or RS killed people each time people not having any direct connection to either party were targeted. the rich and affluent always escaped but the poor were targeted for they belonged to specific casts. Now the question that arrises here is -can we call it collective action ? . it was definetly to some extent a collective action what for what purpose...... and at what cost.?
