Get over yourself. He was a conservationist and worked to do good for wildlife, relocating crocs to prevent them for being killed. His methods were unusual but that was to bring in a TV audience - and it successed. Compare the ratings of his programmes against David Attenborough's of the last 10 years. He knew how to bring in an audience, he never actually killed any of the animals he pursued.
Now if you're gonna say people deserve death because of animal cruelty, then first start with the big game hunters, the fox hunters, spanish bullfighters, fur wearers (particular those that wear rare fur, such as Pete Burns).
It is sad what has happened, but he was always at risk with what he did.
