I don’t know what you mean by violence having some good traits.
Violence can be fun. I’d argue this is particularly true of “safe violence”, that doesn’t result in death or permanent injury. Otherwise we wouldn’t include it so much in every aspect of entertainment, particularly interactive entertainment. We also have people who enjoy violence in their sexual lives.
I suspect the two of you are using “violence” with slightly different meanings.
