I lived in Zimbabwe and understand the need for hunting in terms of conservation both for revenue which funds conservation work and population management given that space is restricted. Each year a set number of licences for viable species will be issued. I have no problem with this in fact with the right connections I probably would have considered a career guiding these tourists but didn’t have any connection to hunting community.
But luring a dominant male head of a pride out of the park to land you can make the kill on is wrong, should be looking to hunt an animal past it’s prime. Also 40 hours for a kill is ridiculous if he wants to use a bow he should be prepared to make the kill the same day. Apart from the animals suffering a wounded lion like that is a danger to people living in around the park. Most deaths among professional hunting guides happen when tracking a dispatching animals wounded by clients.
