Maybe I am wrong, but I was led to believe that joy over the death of others was an unChristian sort of thing...<<
Not joy. Relief.
As a Christian, I am joyful however, when EVIL is destroyed. God hates evildoers.
The bible says God takes no pleasure in the death of the wicked
Doesnt mean they shouldnt be killed ..just that one should take no pleasure in it...
For the sake of your own souls...
However making a difficult long range rifle shot at a moving BG is still a thing to be proud of
