Morality establishes the actions that are considered appropriate and improper in today's society. Individuals in the same socioeconomic contexts tend to overlap and correspond with each other. Other times morals are non-existent or different due to one's upbringing and culture, meaning that "appropriate" decisions seen by some people may be seen as "inappropriate" by others. Evil in terms of morality can be defined as someone's morality is so extreme or non-existent when compared to that of modern society's views that it cannot be understood logically. Despite the effect of morality and education on one's actions, in extreme cases the biology of the brain has a large effect on the distinction between proper and improper. There is a spectrum between correct and improper, it's not all black and white. For example, not tipping well at restaurants and molesting children are both considered inappropriate, but molesting children is significantly worse. A person who commits child molestation does not do so simply because of external factors, but rather because something is wrong with him
