Need advice on playing an evil character

[fishdork74]

Hi! I have always played good characters in all of the NWN modules and I just finished playing NWN2 as a good character. I am disappointed by the ending (to say the least!) and would like to replay the game using an evil character so I can see the much more satisfying ending (or so I have read here). My questions are:
1. What evil alignment (Lawful, Neutral, Chaotic) is the easiest to stick with? I tend to end up with a lawful (good) character with the choices I make if this helps...

2. How evil do I have to be? Do I have to be horrible to everyone? Will this affect what quests I receive? Do I have to be completely uncompromising?

3. Should I always choose the sarcastic/nasty answer when prompted for a response?

I'm having a hard time wrapping my brain around the concept of being evil...I know an evil character can be fun to play, I just want to make sure I do it right.
Any advice is appreciated!

1) It really depends on the player. If you like to lie often, then it is easier to stick with the chaotic evil alignment. If you are crazy about the law then lawful is the way to go.

2) No, it doesn' really affect the quests that are given to you. Only difference would be the sequence of the bandit quests in comparison to the guards quests.

3) Yeah, the conversation options give the most alignment points. So, be as nasty as possible to everyone you encounter.
