to be honest : allthough there are only 3 evil npcs in bg2 they are the best you can get. all the do-gooders suck. really suck. example ? most people love minsc an call him superior fighter ... lol. a "fallen" ranger (cant cast spells) with only 2 points to be distributed in all weapons and styles. pure warrior = 5 points go for korgan.
what about good npc mages ? 3 multi or dualclass women (as lame as charlies angels ...) and no specialist ... hooray ! imoen your tiny sister, annoying voice and childish comments. aerie, no hitpoints no brain silly attributes, jack-of-all-master-of-none. and nalia, USELESS thief and thus slowed in mage lvls. all suck to me. what do we have on the evil side? edwin the conjurer. well he cant use divination but i never missed it. he can cast !8! spells per lvl in later stages, 3 more than these goodie amateurs.
last comparison : healer in your party. ok, jaheira makes a nice fighter healer and can use some spells to buff herself. forget about anomen, he has too low wisdom and how early in the game do you want to finish his +wis-quest? i thought so ... and cernd ? xp-stealer, stops to lvl at 14 (i think) and needs 1.5 mio ! xp for next up. not good. i could list aerie here lol. look at her stats and you know what i mean. but we have a not-so-nice lady here : viconia. pure cleric only healer with 18 wisdom nice romance nice npc-quests as all other evils have too.

so go and create yourself a dualclass thief or multiclass (not tripleclass) and play with an evil party of 4. easy game, fast lvling. whatabout alignment and how to play evil ? viconia sets your reputation 2 points lower as long as she is with you. i suggest to do all the quests and grab the xp and loot. if some quests will reward you with rep-up try to find a single commoner or such and kill him/her. best evil reputation is 5 or 4, if you got 3 or lower the "cowled fools" will teleport in and try to kill you. early in the game they are too strong for you and your party and there is no need to face them or any advantage in it if you win. evil is best in singleplayer (except one situation .. guess it ).

if you want to play a good party create a group yourself (maybe pickup a romance char). to me heroes should be heroes and not lucky-survivors of a harder battle.
