Most religions tend to impersonate evil into some notorious character. You might have eared about the devil, Satan, Lucifer, Iblis, Rahu, Mara, Set, etc. These characters impersonate evil as means to provide a target for the eternal struggle between good and evil.
In the real world, evil is much more real and it is mostly impersonated by a large set of demons often called multi-national corporations. Above all of these, there is one that certainly rules as the pure essence of evil: Monsanto. Funded in 1901, this corporation describes itself as an agriculture company, but has been associated to most chemical and bio-technological blunders affecting human kind, from the agent orange to genetically modified plants. Their aim is simply, to control de world's food production. Their purpose is also simple, to make as much profit as possible, even if that means killing, spreading disease and misery, and destroying the livelihood of millions across the globe. If you don't believe me, look it up. That's what the internet is for!
