If I was to guess my feeling is there hatred for Pakistan is more consistent, persistent and across the board then it is the case for Pakistani's toward India. Pakistani's tend to have a very conflicted, broken, variable hatred for India which ebbs and spikes. The reason is weaker sense of nationalism or a confused sense of nationalism. On top of this their schizoprenia is manifested in the love for Indian movies, Indian songs, Indian food, Indian heroes, Indian culture etc with opposing push by historical memory of migrants being forced out who retain viceral hatred for Hindus but otherwise love/tout all things Indian. And of course the rivalry over Kashmir which itself is a political gimmick.
On the Indian side. Pakistan is just bad. Period. They simply just look at Pakistan as a enemy. A monster that should not been born. Illegitimate child of the British. A feak of history that should not exist. Across the board. A very tiny % of Indians are free from this thinking. This points to a stronger sense of Indian nationalism and a narrative that has been successfully implanted in the Indian pysche by the state.
