Eheh... I wasn't trying to bring philosophy into this. I'm not a learned philosopher, and I totally accept that the game has a black and white view of morality. Maybe kind of grey in regards to the Garleans and Grand Companies sometimes.
Anyway, the player character is a silent protagonist, but that just makes them an extension of the player. In that regard, there is always a choice, doubly so with regard to the totally optional Relic Weapons (what the original topic is about). Takes a bit of out-of-the-box thinking, but there is a choice.
C'mon, give it a shot! Work those brain cells!
