Yes, I believe I will. Man will kill his own species for no reason other then he just wants to do it and it gives a measure of satisfaction. This takes a cognitive thought process. Animals, cats for instance will hunt birds, mice chipmunks etc because they are hunters by nature and if they do not consume them for food they may bring them home as an "offering" to the leader of the pack (it's owner). Cats will fight and maybe kill other cats because they are defending their territory. Dogs may attack other animals if their territory is violated, they feel threatened or they are protecting their master or they are frightened. AS for Raptors and Orca's you will have to link me to someplace that has info regarding them killing, for sport, their own species or other species for that matter.
