I don't know if I would (if I did, I'd end up giving most of the money away anyway, unless I wanted to get myself assassinated in character and body by starting a lobbying group fighting all the other lobbying groups), but if I did, it would be a certain aunt.
Oh, I could tell stories about her. She hates me with a passion, though it seems--at least at first--because she hated her sister (my mom) with a burning passion. But even before that, when I was a (relatively) innocent child (today I think was incredibly innocent, though others disagree, so it's a relative concept, but point is, I'd never done anything to her, even in petty revenge, YET, and I was 13 years old).
She used me to call a friend of hers to gossip. She was scared to use the number because it had "666" in it. Seriously. (Thankfully, most people in my family aren't that crazy, not even the devoutly religious ones.) She was "not taking chances." It occurred to me years later that JUST TO GOSSIP ON THE PHONE she was risking this happening to my child-self (either immediately or later, but in either case, better me than her):
How very Christ-like of her.
So yeah, if I were, she'd be on the sacrificial table. And given that I've learned to hate her back...who knows, if I could get away with it just by giving up everything I own (but not homeless or imprisoned) maybe I would anyway (though really I think she suffers more alive). Though my mom would enjoy it more so I'd let her have the fun. Heck, I don't get along with my mom that well, but if she ever did (for money or just because) I'd never turn her in.
Also, I punched and kicked this specific aunt once (after she slapped me, and other dysfunctional stuff, but mostly made the mistake of directing her hostility to my best friend rather than at me as she usually did), as an adult, and though her (third, which was against the Bible, but she happily ignored that one in her casual hypocrisy) husband threatened to kill me (ah yes, those who love Christ so much that they have to be so hateful, just like they must imagine Jesus Christ to be like), but her adult son told me I was now his favorite cousin. Not many like her. (In fact, many surprisingly took my side save for one thing I did, and even that was seen as provoked. She probably liked that I hit her back as she'd finally gotten under my skin, and hates me more for others, even her own son, taking my side against her. Perhaps I should add that there's a lot of violence in my family.) Though many feel about the same about my mom. And plenty don't want me to move back...but if I do, I'm still less hated than her.
