Ethical problem with animals

I'm working on a prototype for a strategy game where the player manages a theme park with hybrid animals. I love the idea, but there is one question that bothers me. The player is working for a "sinister" corporation. And as one of the gameplay features, I plan to add the possibility to sell the meat of animals. That means the death of animals. Also, there are possibilities of death in other situations, like when animal run away.

Is it ok to show death in a grotesque way? Will it be counterbalanced/justified by the opportunity for animals to destroy the park and kill all the stuff? Or is it just a question of age rating for a game?

P.S.: Sorry for my English!
