I think it's fair to "get mad" at those who produce and profit by making and selling guns and hold them responsible for murders committed with them. Same with Tesla.
In both of those cases the manufacturer knows they can be deadly, and that they cause deaths. I won't make any leaps to try and disconnect those facts.
I make and sell software. If my software was causing folks to die I would stop selling it. It wouldn't matter at all if the users misused it.
