Do good and evil really exist?

Question:

Do good and evil really exist?

Is a lion evil for killing and eating a gazelle, or is it good because it is eliminating the weak and injured of the herd thereby keeping it (the herd) genetically viable?

Some have stated that good and evil don't exist in nature. Take the lion/gazelle example and insert serial killer for lion and soccer mom for gazelle. Could one not make the argument that the human race is overpopulated.

In nature when the ratio of predator to prey becomes unbalanced the weaker predators fall victim to disease, starvation and/or cannibalism. They die until the equilibrium is re-established. So again, does good and evil exist.
