When rehoming any wild critter, you are putting that critter at risk in a country it is not familiar with and will have to compete with others to make it’s living that are already living there.
If it is a prey animal, something will be more apt to eat it there than where it knew the country and where to run to to stay safe.
If it is a predator, you put all prey at risk where you put it, plus both your newly released predator and others already in that area, that will compete and fight for territory and prey.
Just think, one life we don’t take, that one unwanted and dangerous animal you are not killing, but taking away from your area to keep you and yours safe, is now becoming a problem for itself and those where you release it.
Catch and release somewhere else in many places is illegal, just because of that.
We need to think past how sad it is to kill anything, to what the repercussions may be if you don’t kill whatever is a real threat to you and your family and those you are supposed to keep as safe as is reasonable.
Poisonous snakes are some of those.
There is this centuries old story of a man walking down the road between towns.
The weather had changed abruptly and caught this viper out on the road and it was too cold to move, easy prey for the first hungry critter that came along.
The man felt sorry for the viper, picked it up and put it in his shirt to warm it up and kept on walking.
The viper warmed up and started moving and, as the man reached to put it down, it bit him.
As he was dying from the poison, he asked the viper, “why did you bite me, I saved your life!”
The viper answered, "you knew I was a viper when you picked me up … "
Reality is what it is.
No matter how we feel about it and may intervene, that is not going to change what it is.
It is still going to be what it is.
