This character is essentially the captain of his political party's para-military organization.(BTW there are two political parties. The other one uses literal knights as their private army.) He and the organization don't like having people dissing the party that they serve and definitely don't like anyone dissing the State itself.
The problem becomes how do I create reasonable backstory for how he came to hate various ideas of freedom, such as free speech and political transparency.
What could possibly drive a man to such despair that he would break the bones and spirits of those that he perceives as criminals?
Of course note those around him, even the party that he serves (which usually sees this as necessary), criticize him for his ruthlessness and grudges.
