LTPF ,I wouldnt be too hard on myself if i were you.Sadly your father probably over reacted as well and kicking you out was a bit extreme on his part. However I dont judge him for his actions not knowing his background or culture.
No doubt it was a real shock to him your becoming a JW. { and being a pain in the ass trying to witness to him LOL }
I`m sorry to hear that you were never able to reconcile your differences with your dad before he died.
I`m sure their are others here who can benefit from your experience .
Take care.
