What would you do if someone raped your wife? Your girlfriend? Your child?
Inspired by a relevant detail in another post.
What are you capable of? Would it matter if you would get in trouble or not? Would what you are capable of change if you wouldn’t be punished?
Would you stick to letting the law handle it? What if the law wasn’t doing enough? What if you had only your loved one’s word to go by?
The above detail questions are only to brainstorm by. Take the OP as you wish.
