Should dangerous animals be extinct and killed?

Humans are the most dangerous animal on earth..should we kill all of them? No, we should not kill wild animals just because they are wild..your logic is flawed and you should like a very ignorant, uneducated person. ALL animals have their place in the ecosystem..each has it's niche. Killing species can throw off the entire balance of the ecosystem resulting in the end of the human race and the planet itself.
