The answer to this question has to do with the tree of knowledge of good and evil or knowledge of good and evil. In tradition, this happens to be Satan's favorite tree or mode of operation. Those who prefer the council of Satan will also turn what is morally neutral, into a moral judgement of good and evil.
Eve was promised, by Satan, if she eats (learns) of the tree of knowledge of good and evil, she will become like God. This topic is about human subjectivity being used to take the place as God, as the final judge, based on Satan's tree.
The tree of life, like life itself, is not about human knowledge of good and evil, which is subjective, but about the needs of the bigger picture. If the lion kills the gazelle is this evil? According to Satan this might be. But according to life this is the way of life.
If we apply the subjective standard of Satan to the science of evolution, isn't evolution also evil since it often requires killing? Should science be teaching evil since evolution involves killing? The answer is, science is not in the Satan game, like politics, but tries to report things objectively and not subjectively. It is what it is and is part of a larger picture which all integrates together.
