Yeah that whole worrying about innocents bit really screams evil to me, total monster
Not only does it mention him caring about innocents, it also indicates that he once loved Mystra and then tried to usurp her. So it is unclear what his motivations were for trying to do so. They could perhaps be well intentioned things to save people, even if ultimately misguided.
He doesn't have to try to usurp Mystra to be magical Hitler or something crazy like that.
