Which word would be best substitute for savage-minded as it is used in the reading passage?

Please provide the reading passage so I can determine the best substitute for "savage-minded" in context. The best word will depend on the specific meaning intended by the author.

For example, some possible substitutes could be:

* Brutal

* Cruel

* Vicious

* Merciless

* Primitive

* Uncivilized

* Barbaric

Without the passage, I can't give you a definitive answer.
