Why Kosher? – Sparks

The first man and woman ate fruits and vegetables—not animals—in the Garden of Eden. It was only later, after the Flood during the time of Noah, that G-d allowed mankind to eat meat.
We cannot understand the exact connection between the sins of mankind and the subsequent permission to eat meat, but we do know that eating meat is a concession that G-d made. The ideal state of humanity is to be vegetarian.

One suggested reason for this concession is that humanity has an inclination for aggression and cruelty. Humans were not created cruel; they incorporated the characteristic over a period of time. And now that we are challenged with this inclination, we have to figure out how to sublimate it and eventually overcome it.

One way is through the consumption of meat. There is something cruel and vicious about eating meat; it is a way of releasing aggression. But sometimes people have a craving for it. Cravings are really our efforts to express and satisfy a need. Better we satisfy our need for aggression by eating meat than by doing something harmful to people, the Torah grants. Better we not have the urge for cruelty and aggression in the first place, but it is a reality that we now have to deal with and work to overcome.

Judaism does not advocate complete suppression of our negative urges rather it gives us outlets to sublimate them while guiding us to gradually overcome them. Therefore, when we crave, we must satisfy the craving in some way while working towards kicking the habit.

Take a drug addict, for example. There are two approaches to treating the addiction. One method is cold turkey—just stay off the stuff and go through an excruciating period of withdrawal. The other approach is measured withdrawal, which looks like hospital-sanctioned drug abuse but is really medical intelligence. To wean the addict, the doctors slowly administer, each day, decreasing amounts of the drug until the addiction is gone. If a person who did not know anything about this method walked into the hospital, from his limited perspective he would conclude that this place promotes drug abuse as an ideal.

In the same way, there are Torah laws that do not express the ideals of Judaism but exist as a way to reach those ideals. In the case of consuming meat, whether it is to satisfy a craving and sublimate the need for aggression or some other divine reason unknown to us, the Torah temporarily concedes and allows us to do it in the interest of helping us eventually overcome the urge and become vegetarians.
