Do we describe this occurance to be an homicide or fatal aviation accident?
The evidence indicate this was an accident.
Namely the last photo of the helicopter lifting off the ground shows rather clear skies [1]. And the weather is known to change abruptly these days. For example where today where I live, for about 20 minutes at about 3:00 PM skies went completely dark as if it were nighttime and it rained heavily.
The sudden fog later that day looked like this[2].
Anything else being said on the internet with conspiracy theories are just attention hungry idiots trying to get views.
The only reliable source that can change this narrative is the Iran intelligence service. So speculating about it is pointless.

https://isna.ir/xdR8FzThe good side of the death of current president is Khamenie now have to chose another person.
The president of Iran is elected by people's vote not by the leader. The leader himself is also elected through voting! He doesn't "choose" someone to be the president.
The dates for candidate registration, advertisement and the election date have all been set already. It's in about 50 days.
