God we have some awful siblings! I am very sorry for you all. DH had chemo a few years ago and I cannot, just CANNOT imagine anyone buying food that makes a chemo patient feel worse, that is just desperately sad. It's all desperately sad.
Basically his pattern is: work seasonally, move around a bit. Fall out with boss or work out isn't being paid enough, then go to dad's for 'a couple of weeks' which turn into months. He is abroad atm but I suspect will go to dad's for Christmas as dad's wife's sons will be there = an "in" (dad can't deny him a bed if the other two are staying), then stay on for a couple of months.
My grandmother was just telling me how good he is to her (despite his treatment of her son
) as he comes to her village unasked and grits her lane in winter, does odd jobs etc. What she doesn't know is that when our grandfather died, he told me at some length how he used to come to see my grandfather every time he was a bit short, as he knew he'd get paid just for turning up and having a cup of tea with him - my grandfather used to slip him a twenty and tell him to keep it quiet.
He did, actually, at the time seem genuinely remorseful. I suspect he wasn't remorseful at all, but how can you tell?
He also, once, told my dad about the lies he used to tell as a child. He said he planned them meticulously, working out what he would do if a person did X or Y, working through all the possibilities. I think that's chilling.
The thing is that everyone has spent so many years brushing these things off and explaining his behaviour as him growing up motherless. (Our mother is a flake.) When I heard the above story, I said "He should have been a politician." Now I say "I don't think he is normal, I think he has a personality disorder of some sort" and it upsets people. Even though it's so stark staring obvious that most people don't go round behaving in a threatening, dishonest way for a whole lifetime - if they do, it's usually provoked.
I have broken contact with him - well, not deliberately but it has happened. I would like to talk to my family more about personality disorders but I sense it would be very sad for them and if the logical result is that we all break contact with him, I don't know if I can be the one to suggest it.
