I am new to hunting, but I have felt a pagne of regret each of the 4 deer I have taken. It just lasts for a little bit, but they are beautiful creatures and it is sad when they go down. As I get into the work of gutting those feelings go away and I relish the experience of the hunt.
The last deer I took, a big doe right before thanksgiving, I felt a bit more regret than usual as her yearling hung around her body for a few minutes after she dropped.
