Not like this happened intentionally, accidents happen so don't beat yourself up over it.
I find road kill all the time and usually remove from roadways so scavengers dont get it next.
A dead possum, a close look had 3 surviving babies in her pouch. I rescued those, sadly one just too weak didn't live, the others became pets for myself and a friend and such sweet pets, makes up for the short life of others.
I love snakes too, I even rescued bats, just sad when a small life ends, but that is the way of things.
Only guilt trip I had was back when I was 4 I think, I whacked one of those big garden spiders and splattered good. Now I now how harmless they are I still feel bad for that, now I will go out of my way to put them out of harms way.
