I think the verdict was correct based upon the evidence. However, they both suffered abuse as a child which makes them both victims in that sense.
With regards to who was the victim in their relationship, I think they were both abusive in different ways towards each other but Amber seemed far more abusive than Johnny.
Johnny was emotionally abusive in the sense of the names he called her and how he spoke to her in general, in addition to writing on mirrors and counter tops etc. He also drunk a lot of alcohol as well as abusing drugs. I do have respect for him for owning up to what he did wrong.
Amber was physically, psychologically and emotionally abusive to him which is evident in the recordings we heard. She minimised hitting him and mocked him for complaining about being hit. She was also a drunk and dabbled in drugs.
I think both of them should just lay it to rest now and move on. Have nothing to do with each other ever again and both of them not speak about the other in public.
