I don't think the covid vax was made to kill people on purpose for population control or anything like that. That's an extremely normie take that makes other more reasonable theories about it sound more whack than they really are.
I just think that the people who created and pushed for the vax don't actually care about human life/happiness and care far more about turning a profit and controlling the narrative/market. It's never about the people, it's always about the money. If you think about it from that perspective, then purposefully killing people doesn't make as much sense as just not giving a fuck what happens to them.
It's funny that lefties will criticize capitalism to no end but then fall into its trap time and time and time again. All that's needed is a little bit of social conditioning.
