Seductive evil is well and good trope and the implantation of it in this game is really great (assuming it will go where we think it will - the usege of the absolute powers will have some major consequences down the line). However like I said many times before, choosing to use the absolute powers has nothing to do with the "evil path" directly and to put these two story threads together as a inseparable thing might make the evil path look much better than it actually is, but is just not really what's going on in the game.

About evil in the FR - the more I think about it, the more convinced I become that the FR idea of what is evil and its role in the settings is the silliest thing that ever came out of this setting (and this settings has giant miniature space hamsters)

Larian's Biggest Oversight, what to do about it, and My personal review of BG3 EA
"74.85% of you stood with the Tieflings, and 25.15% of you sided with Minthara. Good outweighs evil, it seems."
