Dont beat yourself up over it. My brother was not going to take it, but his wife has mental illness, she spent every waking moment yelling at him that it was good, I am crazy, that he could die if he didnt take the shot. I noticed my brother acting like I was a nut job!!!! he took the shot because she would not let up. Now he says he feels shitty and has a pain in his heart. I tried, you tried. They make their own bad decisions and they have to pull up their big boy pants and live with their decisions and the resultant consequences. I have stopped trying to inform people not to get the kill shots. Fuck em they dont listen anyway.
