The Ontological Argument for the Existence of God

[Angrboda]

No, evil is not the absence of good. Evil is the opposite of whatever we define as good. If it is good to give someone life, taking it away would be evil.

While that may be how you think about evil it really isn't a meaningful way of discussing the relationship between the two.

If evil is the opposite of good that precisely because it good's negation. If it is good have a virtue like, temperance or fortitude, then not having that virtue is not good (i.e. evil), like intemperance and cowardice. Virtue, in Scholasticism, refers to the degree to which something actualizes its Ideal. So for example, a spanikopita (sp) is not as good as a yield sign with respect to the Idea of Triangularity.

Whoah, hold on. Lacking a virtue is NOT evil. It may not be good but it's not evil.
