They did a lot of shit in North America but one of the points of Sword and Shield was explaining how assassinations were mainly directed towards ex-Soviet dissidents and not American citizens. I'm not excusing what the Indian Government did here, I'm just saying that the Soviets (and the United States for that matter) regularly performed actions on this level in a number of western countries.

Sure. But America didn’t assassinate Russians in Russia. And the Soviets reciprocated. This is a bright line that someone stupidly crossed. Rogue elements happen. That New Delhi appears blindsided is the concerning bit.
