Can anyone help me translate this in French and Japanese?: "I hate violence by principle. I only contain..."?

Question

"I hate violence by principle. I only contain it and play about it on my mind"

Answer 1

"Je hais / déteste la violence par principe. Je la renferme dans mon esprit et n'en fais pas cas / l'ignore."

I think the "play about it" means "ignore" or something like that: in French = "ignorer" or "ne pas faire cas" (= to attach little importance to)

Answer 2

The sense of the English text is not very clear, but I give it a shot :

"Je déteste par principe toute violence. Je ne fais que le contenir et l'indulger dans mes fantasmes."
