I have always found Hume's question to be quite interesting:
"Epicurus's old questions are still unanswered: Is he (God) willing to prevent evil, but not able? then he is impotent. Is he able, but not willing? then he is malevolent. Is he both able and willing? then whence evil?" – David Hume
In philosophy we attempt to separate what "is" and what "should be", and this is one reason why a philosophical education is extremely important to develop your own moral compass.
