We at least know he caused the lion great pain in its killing and he gets his jollies in a grotesque way.
It sounds like such hunters may lead to a net good for the animals over there however, and I expect he has suffered sufficiently for his crime.
Well, if his actions lead to a net good, are you against it? Why would you call for his suffering. How do yoo know the critter suffered?
**.......great pain in its killing****
I submit, that perhaps you have never shot a large game animal.
I feel so horribly grotesque!
