Jesus, the pacifist warmonger: is that the great contradiction of Christianity?

Revelation 19:11: “With justice He (Jesus) judges and wages war”

Are there any fact-based refutations of my claim? Over and over in the Bible Jesus contends he is going to be a king and rule over a kingdom eg Timothy 1)—that implies violence in itself. He is also going to somehow transform himself from a peaceful, non-violent person into a raging bezerker and be the most effective battle leader ever known in human history.
I appreciate sincere responses with citations, not emotional feelings with no support.
