Um, no. An evil vampire would not rescue the orphans, because he's evil.
This is where I bring out the Xena example.
We have a person who has rampaged across continents, leading an army that pillages and slaughters all in its path, and who glories in violence and misery. She is evil.
And then, one day, she has a revelation - whether it be through a conversation that strikes a chord, or an orphaned child who sparks a memory, or a divinely-inspired dream... it doesn't matter. What's important is that she's decided to turn it all around, and serve as a protector of the innocent, and fight evil wherever she finds it, etc, etc. And she's sincere about it.
Right now - after her revelation, but before she's changed out of her spikey black armour - what is her alignment?
In my experience, people's answers fall into three categories:
1. She's still evil. Alignment is a record of your actions, and so far she's taken lots of evil actions, but no good actions. In time, perhaps she can climb back up through neutral towards good, redeeming her soul through good works.
2. She's neutral. She can't be considered evil any more, because she's repented - faced with a moral choice, she'd choose the good one. But a good alignment has to be earned through action, so she has some distance to go.
3. She's good. Alignment indicates someone's inclination - it serves as a guide to how they would act in a given situation. Given a moral choice, she'd choose the good one... therefore her alignment is good.
If you have two people who give two different answers to the question, it's very difficult to come to a consensus on a question of alignment, because to them alignment represents two completely different things.
