I had to look that one up. To be fair, the text says that the two bears attacked 42 boys after Elisha cursed the boys, and doesn't mention if the attack was fatal.
Straightforward answers to your questions: No. No.
But, I believe you have missed the point.
It's problematic to send a bear to attack someone -- particularly if you are the all-powerful, all-knowing creator of the universe with other methods at your disposal. Whether or not the victim dies is besides the point.
