I'm a writer too.
Violence for its own sake is generally best to avoid, but when it exists to support the story, then of course it should be there. You've said the story works much better with it than without, so by all means, leave it there.
You could try not to glorify it.
I am a writer too, and I think Christianus Dei is right in saying "you should not glorify it". Certain topics and levels of description are necessary for a story to move along, especially if the story deals with Christian themes like forgiveness and redemption. I mean, redemption is difficult to portray if a problematic situation is not present, and if that situation is full of violence, I think depicting the violence is not wrong in that context. Just avoid overkill on the topic, but only you can pray and decide in your heart what God wants you to write about that.
My current novel is centered around a girl's psychological breakdown after a rape and her regrets relating to a violent manner in which she attempted to get revenge for the rape. I have chosen to write the story as an "after the fact" scenario so reflections on the act are withheld from the reader until the climax (actually, the reader will not know it was a rape that had happened until the last third of the book so the girl's emotional breakdown can be more objectively observed). I still have no reached the part where I am describing that the event was actually a rape, but I have already decided to be vague about the actions, but descriptive about the emotional impact, and I don't think I will actually write the word "rape". The story is about forgiveness, so discussing it at all is definitely necessary. Not all stories with good moral lessons can be all sunshine and rainbows...
