Hypothetically. You wake up every morning from the age of 0 onwards, hearing your parents hate each other, constantly.
Once you're two your father threatens to murder your mother, or you. Your father goes to prison on the basis of these threats. You're able to see him again in 10-15 years.
Or
Once you're two your father threatens murder, it continues on throughout your childhood, you tell your school teachers, you talk to the resource officer, they tell you at least 20 times, "Sorry buddy, nothing we can do." Nothing changes, this is your home life 24/7.
Let me make it clear I would criminize extramarital spouses since there is no divorce, but for our modern world let's say your mother (or father, if you want) is very pious.
Which scenario is preferable to grow up in?
