Whether it is angel interior or devil exterior whatsoever, the
bottom line is that how the the angel shine from the heart. Think
it is the heart that count .....bad exterior can also be behave
like a evil or devil as well with evil thought...right? So, I am
not fully agree what you said ...believe that everyone has its own
good "angel interior" .....and to use devil exterior, angel
interior definition is quite difficult to accept cos it may happen
with nice exterior and nice exterior as well....
