Yes. I wouldn't say it's inherently evil. War and conflict are natural parts of human existence, and unfortunately that sometimes involves canabalism.
But one thing that sets humans apart from other animals is our development of culture. As part of that we've made rules against killing (and eating) other humans in most cases, which is generally advantageous to all of us. So I'd argue it's a strategic change we've made.
