Other people's bad choices are not your problem unless they put you in danger. Don't get upset over things you can't control, be guided by your morals and your gut. If you're here it's probably because at some point down the line you realized something was corrupt in the world being presented to you, so you decided to scratch that itch and wound up in the awakening process.

By now, people who got the shot have made up a good enough reason for why they got it or why they don't care that they got it. In fact, most people I know don't even talk about it anymore, it's just "something that happened" without a thought or a whim as to what the fuck it was all about. There's too much going on in day-to-day lives that the npc's just don't think about the why's and the what's of our system, it's just not in their interest and honestly that's just what they're about. You can't change it through force or pressure, you can't control their programming, but you can be an example of good choices while hopefully planting seeds along the way.
