so for example in 2022 49% for murder. this is death penalty for murder. which most countries used to have (and many still do). and in Iran (and maybe other muslim countries) there is the ghasas, which is death penalty for murder that the family of victim that request. it is not for other killing, like if you kill someone in an accident (car accident).
44% for dug crimes. it means drug smuggler (not user) which unfortunately because of Iran neighboring Afghanistan (a major drug producer) there are a lot of them.
this pressure on Iran for because of "Muh human rights" for death penalty is mostly using this number to say Iranian government is killing dissidents, which in my opinion is mostly bullshit.
this pressure even made many ordinary Iranians mad because the drug destination is mostly for EU and many Iranian border guards and police die in clashes with drug smugglers. this anger was to an extent that there was a call for government that next time EU harrased about this death penalties, Iran should just open its border and let the drug flow to EU.
