Well it is not a matter of why but a matter of adiction. I supposed the people who made soda said, "Hey! Lets just put caffeine in our sodas, and let the peole get addicted so they will keep buying more and more of it." See what I mean? Caffeine is in a way like alcohol, in the way that it is addicting.

i think people add caffeine too soft drinks to make it more addicting.
