A cousin of mine spent a year in prison for manslaughter. Her goofy mean father was choking her brother and she thought her father was going to kill her teenaged brother. So she got the family .22 and shot her father in the head, which ended their problems with him. My cousin was never in any trouble with the law again and is now about 80 years old.
This all happened before I was born, and I would guess there was more to the story. I think my cousin regretted shooting her father, but I do not think anyone regretted his death. He was a mean, bad man, who did a BUNCH of other bad things I won"t go into here. My aunt later married a real nice guy that treated her and her family super well. Too bad she didn"t make a better choice the first time around.
