Demon vs Angel

A demon versus an angel, Who do you think would win a battle like that. I personally a demon would win considering their natural fighting capacity. A demon is more ruthless and is used to using tricks to get what it wants, Many times in media they are depicted as cunning beings or monsters that violently run into things and cause stupid noises, but if you really think about; they are far smarter than that, at least if it is believed that they are pure evil. An angel is far too kind to instantly have a malicious attitude when facing another being, even a demon. The fight would probably start off pretty evenly, both sides fighting and attacking beat for beat, but then the angel would miss the opportunity to kill the demon, not because they want to, but because they are not used to going for the kill. The demon would then use this inability and strike the angel, ending the fight. Of course, the angel could always come back to life, if you think about it. Maybe the battle would never end, maybe it wouldn't even start.
