You might be descending into evil if...

• You ever killed someone to test a weapon. (Gotta see if this Staff of death really works...)
• You ever fed a prisoner, who surrendered and was co-operating fully, to a vampire you were travelling with.
• You ever dumped a prisoner, who surrendered and was co-operating fully, into a nest of alien insects because you promised him that YOU would not kill him.
• You every called an air strike on an undefended village because you didn't like the mayor.
• You ever did the above AFTER killing the mayor.
• You ever sat out a major battle, which you could probably win single handedly, just to see if your strategy works.
• You ever killed someone to liberate their toys.
• You've ever eaten an opponent.
• You've ever decapitated an opponent, and dumped the body and head into seperate vats of molten metal, on the off chance they might be immortal and regenerate. (Always be thorough)
• You ever gave an opponent a weapon, just so you can kill them without violating an "unarmed foe" alignment rule.
• ...and it wasn't loaded.
• You ever caused a war as a distraction.
• You ever intentionally got anyone under your command killed. (Bonus if it's a fellow PC)
• You ever helped the forces of evil take over the world. (The forces of Good never seem to have as much ambition...)
• You ever swore your allegiance to a Dark God to become more powerful.
• You ever swore your allegiance to a Dark God because you though his Avatar was cute (I actually had a PC do this)
• You ever killed someone to keep them from getting powerful enough to kill you, even though they were not threatening you in any way.
• You ever killed something because it looked like it might be threatening.
• You ever killed someone because they didn't believe you would.
• You ever killed someone because going along with them would take too much time.
• You ever killed someone because they were in your way. (Not as in accidentally hit a by-stander who was in your line of fire, but more like running someone over because you couldn't be bothered to drive around him.)
• You ever killed someone because you needed corpses.
• You ever killed someone because there is absolutely nothing out of the ordinary about them (Never trust a smiling DM).
• You ever used innocent bystanders for cover.
• You ever used innocent bystanders as weapons. (Ammunition counts)
• You ever created an undead legion out of a bus load of girl scouts because you thought it would be funny. (It was.)
