I always assumed that eating Bezos or Musk or Zuckerberg was like a holiday dinner. Most of the time you just grab what's easy and cheap, but a few times a year you go out of your way for something special. You put some planning into it to get it just right.
Also it really depends on if these horrible people are actually just mortal sleepers, or if they're like horrible monsters themselves. I did that to my players once - they caught up with Ditch McBonnel and discovered that he was Not Human.
Just go to the courthouse and then you'll be in the buffet of most of the horrible people: criminals, lawyers, judges, cops, rich people suing each other etc.
Just hangout around state and national capitals. Being around politicians would be a target rich environment. Visit the world, eat their corrupt politicians.
All people look bad, after you have become a superior being... (or rather they look tasty, oh uh, I mean, I would guess, answering from a friend, yeah:-P)
Hunt them? There's plenty of "bad" people at Capitol hill, the "rich" parts of towns, silicon valley, NYC, ... Just no Mar E lago, that'll be some serious indigestion and diarrhea.
If you are a monster, would that somehow give you some sort of special abilities too? Maybe flight, shape-shifting, longer lifespan/pseudo-Immortality?
You do get that, but then you have to deal with rich people security and attention. That'd be a game of how many missing politicians/donors can you get away with?
