I always play the same character in my games loosely based on my beliefs and through the ages and mutliple playthroughs it mostly changes only in nuances. That is aided by mechanics like reputation and Karma that have direct consequences in the in-game world and give you a clear political/social and cultural framework of what is acceptable. So my in-born pragmatism also kicks in that I do not generally want to get in trouble with the law.
BG2 (and the alignment system with that) and BG3 do not give me that framework, not enough at least. Reputation at least is mostly irrelevant, and moral choices often have little consequences, yet can net you a huge reward. So the evil choice is also often the pragmatic choice. An alignment system really only works for me, when the prerequisites and consequences are clear, so I can make knowledgeable choices instead of educated guesses.
