Evil CHaracters
The key to taking evil parties through ANY adventure is to provide them with the motivation to do the good things. Money, Power and Fame are strong motivators for the evil party. Let's use Temple of Elemental EVil as an example as I do not have the COin series as yet. The party is evil, the enemy is evil. Motivation, if the Temple rules or destroys the world in it's mad quest to ressurect Tharizdun, what does that leave the evil characters with? No money, no power, no fame, shafted like a virgin on prom night. Motivation would become to destroy the Temple and the cult of Tharizdun so that there is something left to rule when they begin their own plans for conqouring kingdoms and forging empires, or summoning demonic armies to destroy Canon Hazen of Veluna yadda yadda yadda, yackety smackety.
