Is AUTHOR wrong in the post ? POST : I'm the middle of three children, the only son of our parents. Our dad was in his 50s when he had us and his 70s when he recently passed away. Our parents split ten years ago and our mum (she is much younger, only in her 20s when they married) had nothing to do with him and is married to someone else now. When we were children our dad was very controlling/domineering, abused the three of us on a borderline if not outright sexual level on top of mentally and physically slapping us around. This never went to the police and our mum wasn't much better off and treated equally horribly and it took until our dad's frailness started to show for her to finally leave him and take us with her.

As he got older he became physically and mentally weaker, he was diagnosed with arthritis, high blood pressure, had very limited mobility in his legs and needed help to get about so was  considered disabled. Since it took him a long time to get around the home ae needed care to keep him going and my older sister has taken on this responsibility and to a lesser extent so had I. 

Eventually I started noticing that our dad became more haggard/downtrodden in his temperament and sometimes bruises from out of nowhere would turn up seemingly at random, when I asked him he said he slipped trying to take out the bins. Saw it first hand when he briefly attempted to revert back to his old domineering self when arguing with my sister about something and she grabbed him by the wrist and dragged him out of the way. Noticed again when after a bad fall down the steps he asked for help and she seemed to get snappy and told him to shut up and wait. 

Pulled my sister aside  and while she didn't admit to doing anything with him she admitted she didn't care if he died any sooner so we could have him out of our lives and get the inheritance we're all owed. Didn't feel any sympathy for him myself because of what he did to us.

A few days ago he died in circumstances that have me wondering if my sister could have done anything to prevent it and I have a stupid semblance of something running through my head condemning me for enabling her and not doing anything about it.
