A lot statements by authors pointing out that life is brutal, and getting very depressing and deep about the topic, but not really explaining why. Life is brutal because its inherent to all living things being in pursuit of self replication whereupon success, such success is replicated. We are always in strife for the same space, energy, and resources with each other(each other being all living things). Don't be saddened by it, or make it some sort of deep philosophical tragedy. It's as much fact as evolution, or as much fact as 10 - 1 = 9. Accept it and learn to love it for what it is.
