Khameini supplied Russia with Shahed drones that killed and terrorized ukranians for 4 years, Khameini funded and protected Assad who used chemical weapons against syrian citizens, including children, Khameini funded Houthis who starved over 20 million yemenis, he hanged LGBT people publicly and tortured women to death. If you feel his death is unprovoked, you care very little for normal humans and a lot for making sure you arent on the same side as Israel and the US. He got out too easy.
