Snakes that startle me/you aside.
Dangerous, poisonous snakes to me are like the person or dog that threatens you, or tries to kill you or yours. You may avoid it or stop it. But it will/can re-occur. It may be, or is, just the snakes way, same as a villain. Same as a psychopath. There are many, but eliminating one at a time is a start.
A scene in open range where Kevin Costner is going to kill a wounded aggressor as he(Costner) refused to look over his shoulder the rest of his life for repercussions from the aggressor. Now, a poisonous snake does not seek revenge, but left in place it is still a danger plain & simple. Failure to realize this will eventually..........Get you bit.
Kindly remove it from your yard? It comes back later & bites a young child, even you. Not good. The snake does not recognize getting a pass.
Added a bit.
