The sweet, doe-eyed little deer certainly does not look like a people killer, well not intentionally anyway. The deer is not a very skillful hunter and therefore preys on other animals’ food. They do not enjoy hunting on their own, due to lack of skill.
If they are starving, in a predicament and have no option, they will be forced to hunt for anything they can find- and this includes any human in their path. Their horns make them good killers: however their victims will not experience an easy death. So, if you see a deer looking for a meal: stay away!
