On topic, not TOO evil.
This is still the Inquisition and you're tagging along with the 2 hands of the Divine. You shouldn't be allowed to go all trigger happy like in DAO or DA2 and put that murder knife to use.
Because we all know that the Chantry has never committed an act of violence in its history. 
Hmm... let's see.
Well, there was the first Inquisition, which World of Thedas refers to as "a reign of Terror."
Oh, and the Exalted March of the Dales, where the Chantry forced the elves to convert at the point of a sword and give up their homes to live in slums.
And the innumerable apostates which the Church has executed over the years because they might become Maleficarum.
I think it's important to keep in mind that the second Inquisition, of which you are the leader, is not a religious organization, despite the presence of Leliana and Cassandra. Bioware has repeatedly stated that this time, the Inquisition is formed in opposition to the wishes of the Chantry, and that you are more similar to a "plucky upstart."
