same la.
everyone has two sides.
evil and angel.
while the evil always give bad ideas or comments, the angel is
almost as quick to correct it.
as long, u dun put those into actions shd be fine..
my evil thoughts much more evil than urs lor..

evil and good, not angel, Angel sometime also make mistake, like
my colleague, Angel Cupid always arrowed the wrong lovers, ending
up in murders, killing, divorce, quarrelling, fighting etc etc
However, as for evil, if you are good in observing, some evils
are good in nature. And some good can be as evil as hell.
