As I do not get along with my family, I think any one of those would not worry me.

Erasure - I cease to exist in their memories, probably a good thing.
Death of family members - I wouldn't really miss them, they want nothing to do with me anyway.
Never met them - would save me a lot of angst. And they would not have to ignore the fact I exist.

My big sin, I smoke marijuana. Sue me.
