completely ignoring the fact that they all willingly joined for their own reasons
When they joined they did not know what the WG did. Not fully.
For the average Marine (and the world) Oharans were evil. For those high enough to witness it first hand (Aokiji) they saw the reality. Akainu did nit care, Aokiji did.
The premise is not wrong. You either misunderstand or are so caught up in you pl agenda bullshit.
if a policemen goes crook? he will just be apprehended by another policeman
1 policeman is not a one man army that can kill anyone below his rank easily.
And there is a higher power involved. That of MORE THAN 1 policeman. Or firearms...
Not comparable at all.
You just have a ton of baseless assumptions you're trying to force.
For some reason feel your agenda crumbling and lash out. Calm down.
