<|assistant|>
Humans have fought wars for numerous reasons over the course of history, including for territorial gain, resources, power, and out of religious or ideological differences. Greed, fear and a sense of entitlement can often be the driving forces behind conflict and wars, leading individuals and countries to see killing and destruction as a viable means of resolution.
