We know this especially well because earlier fringe attempts to "rehabilitate" the perp have caused widespread offense in India; also as far as can be ascertained, Modi has not given any support whatsoever to these extremist fringe efforts. So any such claim is complete misinformation as well as trying to stoke offense.
Modi and the BJP may not literally worship an assassin, but they absolutely do support violent confrontation against Muslims. The kind of thing that is not only offensive and "fighting words" but a very real existential threat against a minority of Indian citizens. Yet they don't receive punishment because they have the protection of the government. It makes it seem very obvious that this prosecution is just government oppression.

In every liberal democracy. India is not one of those. They have elections, but those are necessary, not sufficient conditions for a meaningful state of democracy to exist.
