This is sickening. I wouldn't object is this man is executed, preferably through a mob lynching.
Meanwhile, abortion is killing hundreds of children today, and no one cares. Alternatively: ISIS is killing people for not proclaiming Mohammed as their prophet. Or: an African-American person is being killed for his skin color. Getting this upset over a lion is ludicrous.
Seriuosly, the guy bought a hunting license and killed a lion with it - if you want to blame someone, blame the government that sold the license.
The real problem is that 9 of each 10 living lions in Africa had disappeared in just one generation and this is a problem because environmental services provided by lions are the direct responsible for saving the lives of a lot of african people each year.
