Certainly you are, or you wouldn’t have said “committing violence against them would be justified”. That’s not justice, and misinterpreting the Bible doesn’t make it justice either.
What do you think would be “justice” for having your own innocent child sterilized and mutilated by having their genitals cut off?
I think the death penalty issued by the victim of the crime would be “justice”.
Perhaps you consider someone doing that to their child an “innocent mistake” which only need be repaired with some jail time or community service?
