There've been a series of posts in this thread - of which yours is the most recent - suggesting that changing the hunter's mind about hunting and eating meat is a big deal. I've been struck by this: it seems that most posters in this thread would require much more elaborate action declarations, and play, to bring it about that a PC converts the hunter to vegetarianism than to bring it about that a PC kills the hunter.
Yes, fundamentally changing someone's mind in a way that forces them to give up their current occupation, lifestyle, and diet is generally hard. Meanwhile killing someone is not an overly difficult task, especially with the mismatch in power between PCs and a typical NPC. Think about it IRL - it would take a lot more effort to convince someone to abandon their career, diet, and lifestyle than to just take the gun you're already carrying (PCs typically go around armed) and shoot them. Obviously you'd have significantly more consequences after the fact from shooting someone than from convincing someone to adopt a radically different lifestyle (one is highly illegal, one isn't), but this isn't about consequences down the line.
