Yeah, Being Evil always was hard in D&D game; the only C-RPG that allowed for interesting evil was Tyranny, which was exceptonnal at that; In BG3, I have yet to see a good reason to be evil except the usual madman, or greedy soldier who would kill anything for gold/bloodlust. We need more smart, political evil like in Tyranny, that allow the player to seize additional power and influence by performing bad deeds. This can comes in many way, including gold, trinkets, but also alternate quest lines. For example, by being evil, you could be offered a easy solution, a privilege, for a latter quest. Or a house with bodyguard and your voice in the druid council. Just an example.
