Are religious people the only ones that use the term 'evil'?
============
A lot of people who are not religious use the term "evil" since it has a descriptive use for the
extremely malicious.
It is strange that a lot of moral philosophy is about what is good and evil has been quite largely
ignored. However, some philosophers take the problem of evil seriously, such as Raimond Gaita in Good and Evil: An Absolute Conception.
