This Ice Age question won't have any answers. If you see it from
their point at that time, their only logic 
chase the
British out and control the plantations that we have to help
themselves.
If you see it from our point of view and at that time, our logic is
we did nothing to harm them, why are they so
cruel?
As for now, when we think back, we still see the same reasons
coming back to us. So it doesn't justify. The Japanese still see it
the same way, they need things, so they go to war, so it's
justified. Our cultures are pretty much the same, whereby we demand
respect for the authority. Those who didn't are punished harshly.
This justified their brutality, at least to them, but not us.
