5.9.2. Is Chinese politician X evil? (中国政客X邪恶吗?)

The term evil does not make sense unless you are religious.

The best definition of evil is a psychopath with zero empathy for anyone: https://en.wikipedia.org/wiki/Psychopathy although this can be better characterized as a disease or extreme personality trait.

The huge majority of those politicians are just regular dudes with a knack for politics but brought up in a fucked up political situation.

Just like you, Ciro Santilli and other politicians in any country.
