Predatory animals

Hello Rabbi,
I recently became vegan (your post on the subject was the straw that broke the camel’s back) and since then I’ve probably developed a sensitivity to the plight of animals, because now when I watch National Geographic and see an animal eating another animal, I can’t stop myself from thinking theological thoughts.
 
I ask myself – why was this terrible concept of predatory animals created? Why hasn’t “a wolf lived with a lamb” always existed? Why did God have to create this evil?
This isn’t really a question about God. This evil makes me think that maybe I need to update my perception of God. I can’t think of a reason to justify this evil, and so God suddenly seems a lot less good to me.
I know that the same question can be asked about other types of evil, such as diseases and natural disasters.
In any case, I wanted to ask if the phenomenon bothers you, and if not – how.
 
thanks!
