Well a good farmer wouldn't have creatures that would suffer, if they were free to roam and weren't caged and didn't torture them when trying to eat them. If you're a good farmer, you won't have creatures that will suffer before they die and are used for meat. I've known vegans and vegetarians that had to go back to meat for certain health reasons so we are definitely designed to eat meat. If we weren't we wouldn't eat it in the first place. A tiger won't eat celery or onions because it's not designed to digest it.
I think we evolved to be omnivores but we still aren't perfectly adapted to handle meat (one of the reasons we cook it) or especially dairy (aside from human mother's milk during infancy)...people have to learn the diet personally most suited for them. If you tune it for you then you can see a lot of benefits.
