Be careful. This comment ("pure evil") is illegal in Germany, under the antisemitism law. Many people got arrested for less. Police show up at apartments unannounced and take all electronic devices. You do not mess around with German law.
It's not being said about a country. It's being said about specific people - the settlers that the BBC witnessed attacking a Palestinian farm.
Neither is it illegal to state that a specific attack by settlers is pure evil nor is it impossible to critizise what goes on in Israel in Germany as you allude in your other comments.
Depending on context (and probably on the judge) calling a person pure evil might be considered illegal. That is not the same as saying it about an attack or other event.
