So an old pup with cancer and an injury put in a strange position means it wasn't raised properly?
You trap me and push on an injury I'm gonna come unspooled too.
So a human with some sort of massive emotional trauma and a drug adiction can be just as desperate, but you and I wouldn't bother to cut one down with lead if he/she became a threat to another man, so why does the dog get special treatment? Rethink that.
