That's because leftism needs an antagonism against the cultural self. I.e. it needs to somehow have an element of fighting against others in your own society.

That exists with say Palestine - it's allows picking a side that's against a western right-wing state, Israel.

It also exists with say Russia, here's a right wing white male traditionalist attacking a state that was aligning towards the leftist EU.

In the case of Iran, there's not really an angle there.

So if you understand leftism not as standing for its claimed virtues and instead being politically akin to a group of teenagers rebelling for the sake of it against their own authority figures, it makes perfect sense that deaths of the downtrodden in general are not of concern - the victimhood cause must resonate with a particular format that gives them a clear and familiar path to self-congratulation - which is the primary goal.
