I still have temper tantrums too. I lash out every few months or so, and a lot of subtle things push my buttons so my family have to tread on eggshells around me. I don't threaten to kill anybody, though. Nobody's scared of me, they just get upset. I am ashamed of being like it and I'm getting help and seeing what meds I will try.
About your father, I don't know. He's 73, so it's not too likely that he's going to change now. He probably has always had a stress disorder where he's been prone to stress, and he also might just be one of those people who are prone to adult temper tantrums. The war can't just be to blame, otherwise everyone who lived in the war will be like that. So he's probably prone to stress and having PTSD easily.
