Are they evil? You see it in the western press all the time.. protests.. blah blah. Does that qualify your statement of evil though? Have you been to Iran? Have you spoken to Iranians living in Iran? Or are you basing your opinion based on the Murdoch, Rothmere led press in the UK? The Israel supporting guardian?
Let me give you an example of press. In Russia, and presumably Iran, everytime there's killings of people like George Floyd, and black lives matter protests, their press says that America kills its own citizens and there are large protests against America. Of course, police brutality in America against its citizens has long been established. Is America now evil? Should we all clamour to bomb America?
No, this isn't about subjective 'evilness', it's all about geopolitics and establishing friendly rulers as they've done in a lot of the middle east, promoted through a narrative pushed by the press in the west. It's not hard to see for anyone that studies history.. but for the average lay person who reads the news and sees 'Iran bad', well that's the extent of their opinion on the matter.
