What was wrong about the British rule in India?

The fact that they didn't get politically involved with the "kaste" system, keeping intact the already existing societal differences and exploiting people of a lower kaste much like nowadays Indian society still has people who have 50 children (ages between 4-11) working for them in a clothing factory, or women of a lower "kaste" in Indian society not having any legal stature in cases of rape, like recently was shown to still be the case.

Hence what was wrong about British rule in India was the fact that they only took, exploited and abused India as a whole, only to leave it intact with all of it's inhumane societal differences. They did not bring democracy, culture of equality.
