Most countries in East and Southeast-Asia are Buddhist / Animistic. The exceptions are the Philippines (Christianity) and Malaysia, Indonesia, Brunei Darussalam (Islam). But also in these countries strong elements of Buddhism and Hinduism permeate people's life philosophy.
The other main exception is of course India where Hinduism is the main religion and 2nd is Islam. However Buddhism comes forth out of Hinduism and as a teaching Buddhism has internationally a wider following.
Buddhism is a religion (or more accurately teaching) with a high level of permissiveness and a low level of absolute evils and necessity for remorse. Although Buddhism certainly has elements of Good and Evil it also has as one of it's main foundations the reality of human nature. Just knowing one acted wrongfully and asking for forgiveness is often enough to obtain this forgiveness without the need for further penance.
Buddhism also includes the Yin and Yang philosophy. One should walk the middle road : Not be too evil nor act too good. One should not merely think of oneself but a certain level of "selfishness" is not only allowed but also accepted.
With these basic elements in mind "Oriental" religion and life philosophy clash directly with "Western" values. For East-Asians in general Good and Evil are not absolute factors in life but rather fluid elements that can change according to the actual situation at hand. This is in direct contrast with "Western" moral values where Good and Evil have absolute moral meanings.
