You do realize that for the vast majority that get COVID, which is the unvaccinated BTW, death is not imminent. In fact the chances of dying are pretty low. Maybe if you actually looked at the stats and stopped following all the fear mongering on the media you'd understand that and in turn understand why one decides they don't need the vaccine to survive COVID.
As far as spreading it to others, if those others are so afraid then stay the hell out of the public. Protect yourself, stop expecting others to protect you.
