Your argument is sort of like saying, just because the British gave them the dynamite, they're not responsible for lighting the fuse.
What happened after the abolition of British Raj was in part a consequence of it, but I would not deny agency of the participants of the warfare that ensued.
I’m going to disagree; however little direct control they exert at that point, the imperial power always bears significant responsbility for the costs of problems that accompany imperial collapse.
It is hard to be honest about our faults and easy to blame others. Balance that against total erasure of the past - denial is rife.
The present controls the past.
Recognize imperial powers’ blame for the adverse results of imperialism doesn’t do that, because blame is not exclusive.
Great Britain (or rather Mountbatten on its behalf) really just acted as a third party arbiter in the partition. It was Jinnah's insistence on a separate carveout for Muslims in South Asia, together with Nehru's refusal to meet any demands for federalism, that resulted in partition. Imperial Britain had nothing to do with Direct Action Day.
