Most wildlife biologists do not support "relocating" any animal. There is good evidence that doing this usually leads to the death of the animal involved, because you have removed it from an area it knows and placed it in to an area it knows nothing about. They can't just walk away in to some forest utopia and live happily ever after. Instead they need to find food and water, along with shelter and safety in a place they have never set foot in. They are strangers in a strange place, the residents of their own species are unlikely to welcome them and instead attack. The relocated animal has to defend itself too, combined with the rest of the issues, resulting in a highly stressed and frightened animal. They are extremely vulnerable to starvation or being dinner for some predator. All of this is ironic because the person doing the relocating did it thinking it was an act of kindness.
Instead of a quick death, they end up suffering physically and mentally before the inevitable end comes.
