It's not bad for us, but we're not meant to eat it so much. You point out that we have canines, but they're small compared to lions and wolves who do need to eat more meat than us. Humans are primates and primates evolved to have a mixed diet. Meat is good, but you still need to eat more fruits and vegetables to have a healthy diet.
Not trying to preach, I'm still gonna eat a good steak lol
