I work in this field last 3-4 year of my life.
Victim will keep suffering if you let the abuse continue. If the abuse stops and you work with them on mending the relationship the trauma and psychological damage is being healed.
Abuser has dozens of factors but all abusers are tied to the root of the abuse which is almost always - lack of confidence, lack of self esteem, lack of parental love and overall lack of attention
And once again, you are clinging to one specific scenario and won't let go.
To be fair, I understand your approach. I think a practical and case by case action is important.
But the person, if committing a crime, is supposed to be held accountable. Now, putting someone in a cell and throwing the key away until the sentence is over, is not the solution.
The State, as being responsible for the well being of the society as a whole, is required to limit the criminal's access to others, as a way to prevent more damage. During this time, it is expected that the State provides the means for the abuser to receive a proper treatment, in a way that, when he/she reenters society, more damage will not happen again.
Not only that, but the victim also needs attention and care.
The problem with domestic violence, specifically, is that it usually takes time before the authorities are informed. It's almost never "hit me once, I go to the police". The victim suffers for different periods of time before any action is taken, IF it's taken.
Financial dependency is also often a factor.
In Endeavor's case, I don't have a problem that he changed, or that his wife and kids are trying to maintain the family together, etc. That's something extremely personal. My problem is that Endeavor faced Z-E-R-O legal repercussions, despite actually being a criminal himself.
Little psyco girl who definitely needs therapy? No no. villain. can never change. she was born like this because me, the author, want it.
Family abuser who screwed everyone around him? Good guy. He saw the errors of his ways. Now he's the big good guy and his family forgave him. Happy days.
Fuck that.
