To be fair, saying the series shows his death in season whatever IS a spoiler.
I know the dude got killed but to discover WHEN that would happen if was on season 1 or 32 is the spoiler
Yep, it took a lot of the suspense out of that episode of that season, because I was spoiled it was happening in that episode, for me.
Of course you know based on history that something is going to happen a certain way, but that doesn't mean you can't be spoiled on the when or even the exact how in a TV show or movie, still.
I mean, sometimes I'll watch something based on historical or real events that I only know vaguely about or purposely don't look up anything about before I watch a dramatization, so you could still get spoiled even despite something being historical fact, as well.
Either way, I agree that it's not a spoiler to state that certain events, like Escobar's death are a thing that happened. But I do consider "Escobar will die this season/in episode X this season" a spoiler for the show.
