No one really cares until one of these kills a few thousand or a few million.

John 12:37-50
37 But although He had done so many signs before them, they did not believe in Him, 38 that the word of Isaiah the prophet might be fulfilled, which he spoke:
“Lord, who has believed our report?
And to whom has the arm of the Lord been revealed?”[a]
39 Therefore they could not believe, because Isaiah said again:
40 “He has blinded their eyes and hardened their hearts,
Lest they should see with their eyes,
Lest they should understand with their hearts and turn,
So that I should heal them.”
41 These things Isaiah said when he saw His glory and spoke of Him.
