My Mother’s neighbour for twenty odd years was a bloody psychopath and she and all of us felt so much better when we found out he was dead! He had chased my then seven year old brother with a knife (which he was charged for- dB had been playing football in the field behind their garden). He hammered sharp long nails into his fence, so if children tried to climb into his garden to fetch a ball they would/ could be seriously injured.
We grew up terrified of him. He loved our dog, so never harmed her but deliberately threw poisoned meat into the neighbour on his other sides (terraced house he was in the middle between parents and other neighbour) garden, killing their beloved Labrador and seriously harming multiple other dogs over the years! He threatened that neighbours daughter with firebombing their house whilst they slept- she was going through treatment for bone cancer at the time. He threw acid on their cars, put nails under my Dad’s tyres, took gouges across every new car my parents or the neighbours bought! Every time they went out, they had to check under their tyres!
When my dh trimmed my Mothers hedge, the next day he came out and started screaming at my Mother about our hedge encroaching on his garden (Which was so unkept and he spent ages burying things there, the council had it dug up later and it was the bones of small animals), my dh (then df) was staying over and went out to (verbally) defend my Mother and he witnessed him pick up a branch and hit my Mother across the face with it! He then tried to attack dh with a pair of secatares (again he was charged). The council were bloody useless, he was sitting a single man on benefits in a three bedroom house, when families desperately needed family size houses.
He was an evil man, his only friend was a fucking evil disgusting old man, who would bring a toddler girl to his house and they would get drunk all day with that poor baby in there with them 😔. My Mum tried to get social services to do something but as he was visiting and we had no idea of his name they could do nothing. The police just held up their hands and said that it wasn’t a crime to take a child visiting. The evil bastard ‘friend’ was later jailed for multiple accounts of sexual abuse of his little granddaughters who he had custody of, as his daughter was a heroin addict.
For years He would hammer at all times of the night and blare music through the walls. When the police knocked on the door asking if she had seen him recently, she truthfully said she hadn’t seen (or heard) him in over a week and she hoped never to have to see him again. The police knocked the door down in a welfare check later that day, he had been lying dead in bed for some time.
My Mother was relieved and glad the evil sod was finally out of her life. The council had to totally gut and re-wire the house, the workman in disbelief asked my Mum if she had problems with our old neighbour. He invited her in to see the house and on both sides where the party walls were, he had long planks of wood attached to the walls, each plank covered in hundreds of hammered in nails and upstairs in the bedroom that was behind my parents bedroom, he had the same but also had massive speakers lined up against the wall.
Personally I think hell is too good for him! But I hope there is a special place in hell for him, torturing him the way he tortured others.
So no, I don’t think it’s wrong that you feel the way you do about your neighbour. As my Dad says, some people are oxygen thieves! If his wife is just as awful, then don’t say anything, you won’t need to, just live your lives as you normally do.
