Our choices sometimes are difficult, especially when there is a lack of trust in God. For example, some people took the shots out of fear of losing their jobs and not being able to provide for their families and yes, then they villify the 'last man standing' as in your case for reminding them of their bad choice.

I remember reading about some kind of psychological test about a train wreck: your can chose to flip a switch and have a train derail causing the death of many or you can chose to not flip the switch and have the train colide with a school bus causing the death of many. What are you going to chose? Sometimes choices are difficult.
