Believe Bamber getting rejected from his natural parents and learning he has a full blood brother and sister relates greatly to the scenario if he is a gulity party
In those days you just crack on with it. No one to turn to no mens mental health, no confiding. Stiff upper lip. Obviously resenment will form over time, to varying degrees depending on the person. Natural bodily reaction.
I have never ever believed it was " just for the cash " although would have been tempting. I believe when he killed if gulity he in his mind was fighting back to a perceived injustice he felt whether it be rrok childhood or anything.
People who knew him at the time describe him as being a " normal sort of fellow" " cocky yes, but I was a cocky git in my twenties ( still am!) as many young men are. It isn't far from the norm. The difference with Jeremy he is convicted of a ghastly crime. I think the reality of his life pre massacre was much more mundane to be honest.
We also have to remember that between both children. Shelia would have took up most of their attention. She had problems of no fault of her own. Jeremy whether you like him or not was seen as a much more grounded person than Shelia.
His adolescence apart from charging money from Nevill to see the world was a lot less troublesome. He displayed no obvious mental health problems. Nevill would have been more sympathetic to Shelia as she was probably a daddy's girl in many ways. When Jeremy approached Nevill with a problem it was probably met with a curt response of something like " just stop moaning Jeremy get on with it"
Nevill and June were still babysitting Shelia in her late twenties, Daniel and Nicholas, hospital stays, Nevill having to drive down to London to comfort Shelia in the middle of the night ( whilst having a business to run and maintain ) June by Adams submission " cooking for Shelia and taking meals to her "
But when I say "babysitting Shelia " I don't mean it to her detriment. She wasn't a well woman. She just needed looking after.
Seems Jeremy just wanted more dough from them. To be honest there's nothing much to differentiate Jeremy from a lot of young men in that regard. He seemed to like the high life and expensive tastes. I would have probably been the same if my parents were wealthy. My grandfather was wealthy and I was spoilt by him. Getting cars bought off him and such and other things. The only difference is my grandad was happy to offer me and my siblings these things. It wasn't a case of us saying " I want this I want that "
David Boutflour mentioned that June and Nevill were soft with both children and not strict. But I don't see Nevill or June to be pushover sort of people.
Well, the odds here are really stacking up against JB, aren't they? You've pointed out, quite rightly, that back in the 80's there was no help for men who had problems of the psychological type -and let's be honest, if JB had even thought his 'problem' to be any more than controlling parents and a spoilt sister, he'd have thought the next step would have been the "loony bin"- but it doesn't mean they didn't have those problems.
So now you've added sibling rivalry to the mix! Whilst, in most families, it's par for the course and a normal part of growing up, ie, Why do I have to go to bed first? Why don't I get as much pocket money? I wanted that one! etc, etc. Usually, the natural bonding between family members kicks in and straightens things out. However, in some families, the rivalry can become much darker -usually, and in my experience, where significant wealth is part of the equation. So, from a young age, we have JB, before he knew he was adopted, knowing he'd come into megga money when he was older and all he had to do was fulfil certain obligations, but he probably saw his sister as getting everything she wanted without have to fulfil anything -NOT saying this was how it was, rather, it was as JB saw it unfolding. Clearly, the Bambers tried to balance the financial handouts. They paid for all Sheila's post school courses to find a suitable career, so they paid for JB Australasian trips, but it all stopped when Sheila failed at everything, other than becoming pregnant, and they subsequently provided her with a London apartment which, in the 80's was the place to be, and undoubtedly, JB longed to be there,,,,,,,,,,,,,except, for him, the handouts came to an end and his 'obligations' began. He probably saw that as being his life mapped out indefinitely. He had a choice. He could stay with it till he was middle aged, watching Sheila and her growing boys suck his inheritance dry, OR, the alternative was to take matters into his own hands.
