There is just another side to this issue. Say I want to roleplay an ''evil'' character, if a random woman asks me to find her child I will tell her to fck off, because looking for lost children is not something an evil character does, but the good guys will get the XP for that quest. Solution? Just murder the woman and get the XP. If you don't get XP for killing NPC's then you only reward the good characters instead.
