This "discussion thread" is degrading.
Unfortunately, it reflects reality.
No matter how much one does not mean it badly or greedily, it often does not come across that way to other parties involved. Entire families often fall apart over inheritance.
Unfortunately, many testators do not see their responsibility, which they should take on before death to prevent the worst problems afterwards. I don’t just mean legal clarity, but discussions within the entire family about who gets what and why, what is arranged how and why, etc. – until all future heirs feel acknowledged and understand.
Very few people make that much effort, because the dear children are supposed to always get along well, please, please...
