Stabbing the bartender in the face for no reason, sexually violating his wife and daughter, and mutilating his sons is evil.
I'd argue that it's also pointless. And more on the psychotic side than the evil side. Or inhumanly twisted. What's the percentage in stabbing a bartender in the face? That's not evil per se, it's a bad parody of the hockey masked villain or the striped shirted janitor with claws in a slasher flick. It's completely pointless and doesn't serve any motivation other than "let's derail the plot." Evil is about "Me, me, me!" not "Let's see how many people I can stab in the face before the DM sets an angry mob on me." Maybe the bartender can be bribed or intimidated into telling you something you could profit from. Maybe you blackmail him, or threaten his family if he doesn't comply. That would be evil. If I was interested in such a campaign (and I'm not.)
That would be a "turn in your character sheet" moment for me. Whether it was a good, evil, or neutral campaign, that's more like plot derailment than any kind of constructive roleplaying.
That's the whole problem with the alignment system, IMHO. It's people acting on what they think is good or evil in the spur of the moment, without actually considering motivations and consequences, long term goals, and so forth. Instead of putting yourself into the head of the character, you put yourself into a box, then either completely ignore the box or try to do stupid and annoying things all the time to say "look, I'm roleplaying!"
Want to convince me you're good? Tell me, Mr. Cleric, why did you just spend six days in that village without once bothering to see if there was anyone there that might have benefited from your cure disease spell? Hmm? Guess you're not all that good. Want to convince me that you're evil? While you were busy doing totally random and pointless things to sheep, puppies and barmaids there was a perfect opportunity for you to advance your plans just around the corner.
Better to leave out alignment so that people actually have to think about their roleplaying choices.
